Stolen from SB board
I have a few. Two that stand out are:
The beginning of Up! I HATE THIS MOVIE. I SOB LIKE A CHILD AT THE DENTIST. ITS AWFUL. But I could watch this scene over and over again. But I'm seriously a blubbering idiot. http://www.youtube.com/watch?v=GroDErHIM_0
And the part from the movie Easy A (which I like too much) where the gay guy comes over and the mom says she has a gentleman caller and Olive makes a joke about her dowry and booze and stuff.
I can't find a clip of that though.
