Thought I could bump this up a little after having thought of two short yet laughable scenes.
1. In "The Otto Show", Homer remerabers back to his teen years after his first rock concert. Camera pans to a cliff (I don't think this is Springfield Gorge) where you can hear Homer moaning and the car starts swaying two and fro. It turns out he's just moaning in the pleasure of all the food he has in his car.
2. On the episode where Homer gets a DUI, Homer goes to an AA meeting and Chief Wiggum is about to start the movie on how drinking and driving is bad. Unfortunately, he accidently had the wrong video in which he was laying in a kiddie pool eating a hot dog :lol:
I think what was funny about that was that the lady in the crowd screamed at the sight of that :lol:
