The Skipper is unable to remember how he fixed the transmitter from his Navy days, so he attempts to have the dream again, but is unable to fall asleep. Each castaway attempts to help by sneaking two tranquilizers into Skippers mango juice. When Gilligan hits the transmitter out of frustration, it suddenly works! However, when he hits it again in an effort to show the other castaways how he fixed it, it falls completely apart just as the plane flies overhead.
