My favorite comes from Super Mario RPG for SNES.
"Who do you think you are, Bruce Lee?"
This is when Mario is trying to punch everything in sight (I think in the forest) and Mallow scolds him.
To make things better, I played this game shortly after I had a student teacher whose name was Mr. Lee. He looked almost exactly like Bruce Lee, only younger (his name actually did begin with a B, but it was Brian or something like that). Having this guy fresh in my mind, the quote made me almost pass out laughing. Got a few funny looks from my dog over that!! Not sure what happened to Mr. Lee after that though--never had him as a sub or anything the next year.
