In Sunday's episode (April 29, 2012) of The Simpsons, they go on a cruise, but thanks to the cruise director's song, Bart realizes that his cruise is going to come to an end, and from there, after experiencing all a cruise has to offer, his life is going to be all downhill from there. (As we all know, that's only true until our next cruise.) But Bart plots to keep his cruise going forever.
In the clip below, cruise director Rowan Priddis, voiced by British comedian Steve Coogan, sings "Enjoy It While You Can" (an original song for the show), and Bart suddenly makes his horrifying realization that it's all going end.
