OK, I'm a poor Simpsons nerd -- I can't remember which eps these things are from:
1. "Now, without further Apu..." Apu: "Oh, I have been zinged..."
2. Marge is talking to Bart in his bedroom when a saw cuts from below cuts a circle into the floor and then Homer pops up, sez, "Uh oh" and drops back down.
Uh... more to come, possibly.
