I'm surprised I'm the first to mention it -- I thought it was kind of interesting when Homer did that thing where he said "There is no way I will put on a nun costume and infiltrate the convent! No way!" and then a transition happened and he said "See, what did I tell ya?" It's a funny joke, but unfortunately Family Guy beat them to it by 10 years (wow, has it really been that long?). I'm not going to be naive enough to say they stole the joke; it's a clever subversion that The Simpsons should have done first, but they didn't, so now I really can't laugh at it.
Cletus did the real version of the puzzle. And failed.
