Jesse is back home from the tour that he and the Rippers went on over the summer, and an ultrasound shows that Becky is carrying twins. While this thrills Becky, the same can't be said for Jesse, who feels afraid of what is now a double responsibility that awaits him, because he doesn't want to mess up in any way as a father. The family helps Jesse come to grips with this fear, and Jesse is happy about Becky carrying twins, and they have told Dr. Sinclair that they want to wait until birth to know what gender the babies are. Meanwhile, as the new school year starts, Stephanie is nervous about entering 4th grade, until she meets her new teacher, Mr. Lowry, whom she now has a crush on. Michelle is worried about what kindergarten will be like, until she befriends Teddy, one of her new classmates.

After a talk with Teddy, Michelle realizes that she doesn't know how it feels to have a mother, so in order to have a mother, Michelle tries to find a woman for Danny, and Michelle believes that her teacher, Miss Wiltrout, is exactly the one she's looking for. Meanwhile, when a record company tells Jesse that Jesse and the Rippers' image is too soft, Jesse and Joey work together to try to come up with a tougher image for the band, and D.J. is writing an essay for school, and it's titled "What it's like to be someone else". For this essay, D.J. temporarily switches places with Kimmy.

D.J. is absolutely fed up with Stephanie. Therefore, D.J. petitions the guys to let her have her own bedroom -- something she hasn't had in 4 years. The guys talk it over, and they decide to let D.J. have her own bedroom. D.J. feels relieved, after four years of sharing a bedroom with Stephanie. The new arrangement is that D.J. and Michelle will switch rooms, and as a result, Michelle will be Stephanie's new roommate, while D.J. takes over Michelle's old bedroom. Problem is, Michelle doesn't want to be Stephanie's roommate either, making Stephanie believe that no one wants to live with her. For D.J., this puts the prospect of having her own room in jeopardy, until she helps Stephanie accept the change, and they help Michelle accept the fact that she'll be Stephanie's new roommate.

Todd Mitchell, one of high school freshman D.J.'s schoolmates, is spreading a false rumor around school that D.J. is the worst kisser. It's Todd's way of getting even with D.J. for refusing to let Todd kiss her on the way home from the library. D.J. shows Kimmy a sympathy card that D.J. got from Kathy Santoni, who, on the card, refers to the situation as a "mega crisis". Later, under the guise of collecting dirty clothes to take downstairs to the laundry room, Danny goes upstairs to D.J.'s bedroom while she's not there and finds the card. The term "mega crisis" arouses Danny's curiosity, and he wants to know what D.J.'s mega crisis is. Later, at a bowling alley, Danny is spending some time with D.J. when Kimmy shows up and takes D.J. to the mall, where Todd Mitchell is continuing to spread the rumor. At home, Danny slips up and mentions "mega crisis", indicating to D.J. that Danny has seen the card.

A record company tells Jesse that if he can write a song that can be a hit, Jesse and the Rippers will be signed. When the family prepares to go to Lake Pollock for a big family reunion, Jesse, who is frustrated by his lack of song ideas, says in an angry way that he can't go to Lake Pollock with the family. Later, in a diner, an Elvis Presley impersonator helps Jesse realize that he was wrong to lose his temper and snap at the family, and that his obsession with writing a hit song for the record company has made him forget how important his family is to him.

Joey feels like his life is going nowhere. He doesn't want to read a bad review of his last performance, and he doesn't have to, because the newspaper's employees are on strike, then the KFLX radio station calls and asks Jesse a cartoon trivia question that Jesse can't answer, but Joey answers it correctly, winning tickets to the Donny and Marie reunion, then Linda, an attractive technician from Hilltop Cable Company, comes over and puts a booster on the cable out back, then comes inside and works on the TV. Now channels such as the Truck and Tractor Pull network are available. Before leaving, Linda agrees to go to the Donny and Marie reunion with Joey. Jesse and Joey then sit down to watch "Wake Up, San Francisco". The first guest is local children's TV show legend Ranger Roy, who is Joey's childhood idol.

D.J. has promised to be the judge, so at the end of her visit with Eddie, D.J. tells Eddie about the dog show. Eddie wants to see the show, so he sneaks out of the nursing home and goes with D.J. to the house. At home, D.J. notices Eddie acting strange, like he doesn't know who D.J. is.

Stephanie's dance teacher has told Stephanie that Stephanie has the potential to become a professional dancer. It would be a dream come true for Stephanie, but it means taking special classes before and after school and on weekends, an earlier bedtime, and less TV. Stephanie convinces Danny to let her have a shot at it. As a result, Stephanie no longer has enough free time to spend with friends and family, and she has a dance recital coming up, and Danny is more excited about it than Stephanie is. On the night of the recital, Danny tells Stephanie that if the director of the Bayview Dance Academy, who is in the audience, likes Stephanie's performance, Stephanie can get into Bayview's summer dance camp.

It's Michelle's 5th birthday. Michelle is afraid she's about to lose her status as "the baby of the family", because Becky is pregnant. Michelle thinks this status is what makes her special. As a result, even though she can't stop it, Michelle doesn't want to be 5 years old. As the family convinces Michelle that she's special to them no matter what, Jesse is having what he thinks are sympathy pains.

Michelle's birthday party has just started when Becky announces that she's going into labor. The twins are coming, and she needs to get to the hospital, fast. When Jesse leaves to take Becky to the hospital, the others stay behind to speed up Michelle's birthday party so they can get to the hospital to be there when the twins are born. At the hospital, Jesse's "sympathy" pains turn out to be appendicitis. As Jesse undergoes an emergency appendectomy, Danny is the one who is at Becky's side for the time being. After the surgery, Jesse is placed in the maternity room that Becky is in, and even though he went through an operation, Jesse is still at Becky's side when Becky gives birth to twin boys. Nicholas "Nicky" Katsopolis is named after Jesse's father, and Alexander "Alex" Katsopolis is named after the teacher who inspired Becky to go into journalism.

Becky and the twins come home from the hospital, and Becky's doctor has mentioned that it's common for new mothers to have mood swings. Nicky and Alex are still wearing their hospital bracelets. Michelle feels left out when D.J. and Stephanie are allowed to hold the twins and Michelle is not allowed to. Becky wants to take a picture of Nicky and Alex for her mother Nedra, but Becky wants Nicky and Alex to be wearing the booties Nedra made for them, but Jesse doesn't think the booties are manly, and he wants the twins to look manly. Later, Becky removes the bracelets from the twins, but leaves the booties on the twins so she can tell them apart. Minutes later, while Becky is out of the room, Jesse removes the booties from Nicky and Alex's feet. It takes Jesse only a few seconds to realize that now he can't tell Nicky and Alex apart without the bracelets and the booties. Jesse and Becky finally let Michelle hold one of the twins, and

Danny introduces Vicky to the family, and Bay City magazine has chosen Danny as their bachelor of the month. When the issue that Danny is in is released, a lot of women start asking Danny out on dates. Because of this, Danny is out virtually every night, and Michelle misses Danny being home to tuck her in at bedtime every night. On "Wake Up, San Francisco", Vicky accuses Danny of being a shallow date even though she has never dated Danny, and as a result, Danny asks Vicky out so she can experience a date with Danny. When Danny and Vicky go on their date, Michelle and Teddy stow away in Danny's car so Michelle can be with Danny. A few minutes after arriving at the restaurant, Danny sees Michelle and Teddy sitting at a table close to the one he and Vicky are sitting at. Danny talks to Michelle, and apologizes for not spending much time with her lately. At home, Danny and Vicky share a kiss. Meanwhile, in the attic, Jesse has f

Michelle wants to learn how to ride her bicycle without the training wheels on it, and Joey volunteers to teach her.

After all the adults have left, Steve Peters, a boy from D.J.'s school, shows up to take D.J. to the movies. Problem is, Michelle has the sniffles and is not allowed out of the house while she has the sniffles, and Stephanie needs to finish her book report. D.J., who desperately does not want to miss out on a date with Steve, decides to remedy this problem by taking Michelle and Stephanie to the movies with her and Steve. Problem is, between Steve and D.J., they don't have enough money for Michelle and Stephanie to get into the theater, but Kimmy happens to work at the theater. D.J. talks Kimmy into letting Stephanie and Michelle

It's time for Becky to return to "Wake Up, San Francisco", and Vicky has received an offer from a TV station in Chicago. Jesse, after yet another record company has rejected him, is now the only one who stays home with the kids while Danny, Becky, and Joey work at the TV station during the day, and Jesse's pride is hurting because Becky is the one who earns the money, while Jesse is like a stay-at-home mom. In order to solve this problem and start earning money, Jesse gets a job at an airport playing with The Diplomats, the airport's lounge band, and at the airport, Becky convinces Jesse that the fact that Becky earns the money and Jesse is like a stay-at-home mom does not mean that Jesse has become the weaker gender in their marriage. Also at the airport, Danny says goodbye to Vicky, who has accepted the offer from the TV station in Chicago, so Danny and Vicky will be maintaining a long distance relationship.

It's Stephanie's 10th birthday. When Stephanie hears that Tommy Page, her favorite singer, is scheduled to be a guest on "Wake Up, San Francisco", she begs Danny to invite Tommy to her birthday party, but Danny refuses.

Stephanie just happens to have a monumental crush on Tommy, but Stephanie is devastated when she later sees Tommy and D.J. kissing. Stephanie declares war on D.J. for this, until Tommy helps straighten things out between them.

Meanwhile, Joey helps Michelle realize that she must stop annoying Stephanie whenever Stephanie has friends over to the house.

Danny arrives home from work, and notices that the girls are in a bad mood because they haven't had a good day. Neither has Joey, who would rather forget that day's "Ranger Joe" episode.

Danny and Joey and the girls go to a pirate themed seafood restaurant, where D.J. is afraid she'll be embarrassed in front of her classmate Shelly Phillips, who is also at the restaurant, and Joey and the girls seem to get a little more bitter, but they lighten up when they are forced to "walk the plank" -- right into a pit full of balls.
