So Greg arranges for Kim and Christine to go a day spa, giving him and Jimmy a day alone with the kids at the park. Jimmy gets hot at the park, and talks Greg into taking the kids someplace else that's cool -- a casino. Greg catches Sam on tape taking his first steps in the casino lobby, but then realizes that he can't show the video to Kim because of where it was taken.

When Greg's just about ready to give up, Jimmy tells him how he got Dominic and Logan to wean; he'd dress up like Christine with a bottle shoved under her clothes and pretend to be Mommy. It works like a charm, after which Greg finds out that Jimmy made the whole story up. The next night, Kim c

Worked up from the club, Greg surprises Kim with a night full of passionate sex. Kim is ecstatic at first, but then flips her lid after Christine fills her in that the reason Greg was so passionate was because he and Jimmy went to a strip club. Jimmy advises Greg that he should pull a repeat performance of the night before with Kim, so she'll know it's her that's putting him in the mood and not a bunch of naked girls. After Kim has a chance to cool down, she and Greg discuss what they should do in the future to turn each other on.

Kim's and Christine's father, Don Ludke, comes for a surprise visit. Greg feels left out as Don has never liked him -- and still doesn't.

In an effort to impress him, Greg tries to build his own jungle gym, but it falls on top of him while he's working on it.

After Greg and Kim drive a set of friends away with their dull parenting stories, Kim fears they've become a boring couple. To try to make things interesting again, she sets aside ""talk time"" for her and Greg to discuss current events and anything not related to Sam. Talk time bores Greg, though.

The Warners' ongoing feud with a crazy neighbor, Walt, escalates after Walt demands Greg cut down a supposedly unsafe tree on his property. Greg solves the problem by calling a town inspector, but it indirectly results in a bigger problem when Jimmy lets the inspector know that he and Christine are living permanently in the Warners' guest house -- which is against the town's zoning regulation. The inspector tells Greg about a waiver that would allow Jimmy and Christine to continue living there, but everyone on the block would have to sign it... including Walt. As he wants Jimmy and Christine to move out, Greg doesn't even bother to tell them or Kim about it until after he experiences a guilt trip over the possibility of the Hughes living miles away in poverty.
