Hands down, I think one of the funniest Family Guy clips is probably one of the most subtle ones and likely not everyone else's favorite. Here's the premise:
Peter comes across some protesters with 'Free Tibet' signs. He runs up to one and say's "I'll take it!" and then immediately runs to a phone booth. He dials a number and and says "Hello China? ... I have something you may want ... that's right, all the tea."
It's a well written joke that guaranteed, went over the heads of MANY people. Yet it makes me crack up, even playing it in my own head. Is that wrong? Is it too soon? Probably on both ... that's what makes it funny.
Go look it up or watch the episode it's on. If you don't get it, try reading something other than TMZ once in while.
Bonus: 500 Internet points if you can find a GOOD clip of it (please share if you do).
(I can't find a good clip of this one on YouTube, but had to share since it was in my head ...)
