Son: Dad! I learned an awesome new trick at school in science class. Can I borrow your tie?
Dad: Letís see it.
Son: if we fold your tie in half, and roll the fat end toward the middle, and the thin end toward the middle, we have two rolls Ė one big and one small, both the same length, right?
Well, if I hold up the tie from the middle, and let go of both sides at the same time, which side will unroll first?
Dad: I have no idea.
Son (drops both ends, which open at the same time): Itís a tie, dad.
I have a short attention spa
