One of my friends at school once commented that a a lot of the time when I'm around people everything I say sounds like it was from a movie.

Another thing that I do that I'm fairly sure nobody else I know does is how I answer the door. No matter who's knocking on the door I creep up to it, jerk it open as fast as I can and say, in the creepiest voice I can, "I've been expecting you..."
I think I seriously freaked out a package delivery guy once... it was hilarious...
