Quite similar to, but not as involved as Three Man. Still, a high buzz factor.
Roll two dice. Anything that adds up to six (i.e. 2-4,5-1) or has a six in it (i.e. 6-1, 6-2, 6-2, 6-3, 6-4, 6-5), you drink a "good" gulp of beer. Any time you roll double 2s, 4s, or 5s you drink that many (2, 4, or 5) "good" gulps of beer (You can modify this to just one "gulp" on doubles). If you roll double 3s you are penalized twice, for getting doubles and adding up to six. Thus four "good" gulps (or 2 if you play the modified rules). The killer is double 1s or double 6s. For this you do a SHOT of your favorite poison (i.e. JD, Southern Comfort, tequilla, etc). Lastly...you continue rolling until you get something that you don't drink on (i.e. 1-2, 1-3, 1-4, 1-5, 2-3, 2-5, 3-4, 3-5, 4-5). If you roll the dice off the table, you are also rewarded with a gulp of beer.
