I LOVE this thread!! Ok, I have a book, it's called Lifes Imponderables, by David Feldman. It has a TON of these types of questions in it. Like why do clocks run clockwise, stuff like that. It is the BOMB!! Oh, I am with you, I love randomness!! I wish I had the book with me at work, I would post some of the questions. Ooh, maybe I'll do it when I get home, if I remember!
