I make an insane amount of movie references from movies I haven't even seen before, but only seen clips or heard quotes from.
I've been watching this thread for a long time yet never confessed anything myself.
I dislike half of the folks I have on my Skype/Steam/GTPlanet friends list (or followers, for the GTP laymen) but I don't want to be rude or plain old mean and delete them.
I once stole two bucks from my 6 year old sister to help pay for the rest of my pizza. My pizza.
Whenever I go to a party, I occasionally grab a snack or a drink that is being handed out even though I'm not either hungry nor thirsty, and I find a place to hide the snack or drink. And yes, I leave it there when I leave.
I pretend to be a bit of a tough guy when I'm driving with other people in the car, but when I'm driving by myself I'm as nervous as Velma without her glasses.
