Bicycle Rider Back Playing Cards
Nothing beats the classic Bicycle deck of playing cards for an endless source of entertainment at a college party. Play King's Cup, Screw the Dealer (or the less appropriate name), or one of the numerous other drinking games based on a deck of cards. Great fun and truly engaging.
they're cheap enough that you can get 5 decks and they are the all time playing cards. with a little imagination you can amuse yourself for hours (and hours) with these simple little cards. gotta love it.
