Well, this episode looks like a blunder to me. I just saw the commercial. Homer seems to break his jaw be running (without looking of course) face first into a gold statue of Drederick Tatum (or some boxer). It then shows Homer bonding with Bart, Lisa, and Marge, but I think the tone of the episode was ruined right away in a scene where Homer and Marge are dancing at a romantic place:
Marge: This is the most wonderful evening I've ever had.
Homer: (through his jaw wiring) I'm..horny!
Doesn't that sound great!? :rolleyes If you're gonna miss an episode, I have a feeling this will be a good choice.
