Addition:

No sooner had Geoff (my cousin) and I taken our seats in the movie theatre, than the fellow next to me (quite attractive, too) turns to me and holds out a deck of cards, fanned out.

"Pick one," he says.

I do, because as anyone knows, I'm a sucker for card tricks.

"I bet I can tell which one you've got." He flips the deck over, and starts sifting through.

The cards are in suit order.

It still takes him three passes through the deck to tell me I took the six of diamonds.

I love geeks.
