WTF, gambling at midnight? 21st birthdays are supposed to be about challenging your liver to a battle, you gotta show that little [censored] who's boss. Be sure you meet the required quota before hitting the casino--watered down casino drinks DO NOT count. I recommend the following progression:

1) beer
2) beer
3) beer
4) beer
5) beer
6) beer
7) beer
8) beer
9) three wise men
10) prairie fire
11) rusty nail
12) cement mixer
13) 151 (this will be hard after the cement mixer)
14) Jagr bomb
15) butterscotch schnaps
16) beefy shot (good luck)
17) slippery nipple
18) lemon drop (for the ladies)
19) three wise men redeux (reaffirm sexuality)
20) boilermaker
21) mind eraser
