While watching The Big Lebowski, every time "Dude" is said, by any character, one must take a sip of a White Russian. When The Dude pours or drinks a White Russian, one must FINISH theirs. When The Dude smokes a J, one must smoke a J. Excellent way to spend an evening.
Man, we've been planning The Big Lebowski Challenge for weeks. We've got 4 gallons of milk, 4 handles of vodka, 5 fifths of Kahlua, a gatorade cooler, and half an ounce of greens.
