When watching The Big Lebowski, to drink a White Russian whenever The Dude drinks one, and to smoke a joint whenever The Dude smokes one. This is very difficult as there are around 12 White Russians and 3 joints in the movie.
Alex: Let's do the Lebowski Challenge tonight!
Ray: Naw, I don't feel like being in a coma for the next 2 days.

While Watching the Big Lebowski, every time the dude drinks a white russian, or smokes a joint, you must too.
We're going to the store and to see my dealer, because tonight we're doing the Big Lebowski Challenge.

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.
