You could play a card game called "Mao", that's the most adictive (and confusing game I;ve ever come across.
If you want to try it out, here's an explanation I did while back:
Seraphic Forums: Acting Behind the Scenes - Mao, the most complicated card game. - Telekinesis, TK, PSI, and all the other Kinetics
I definitely recommend this... nothing like a few hours of Mao to kill time!
