I tried my best to search through all the posts concerning the premiere, but didn't find anything about the couch scene... forgive me if I'm wrong.
Anyway, what was the meaning, or "joke" of the couch scene? The family is on a (simply drawn) boat, then they jump off and they're on the couch with water splashing. I have to imagine there was something I was missing, some reference, especially because of the way the boat was drawn, like a child's drawing.
I know one of you Simpsons smartees can explain.
Thanks, UB
