Penalties, usually time, are imposed for spilling beer or vomiting.
Variations on the rules exist:
The beer can be a 36 pack instead of a 30.
The amount of marijuana is sometimes reduced to 2 grams.
The puzzle is sometimes more pieces, depending on how long the participants want the competition to last.
Also, some competitions change the order of events to account for the Beer before bong rule (that's just wrong).
Another variation exists wherein the teams begin in the morning, can drink, smoke, and eat simultaneously, and then once everything has been consumed, may move on to a 1,000 piece puzzle. The teams have until midnight (or in some cases, sunrise of the next day) to complete the challenge. In this variation, the challenge is more geared toward "getting it done" than racing and can be performed by a single team of four if desired.
"No, the other one."
