Just A Quick Game:
If you don't want to bother with cards or are at a bar and want to play, just poll the audience. No cards, no numbers, have one player read the question and everyone points or shouts their votes. Whoever loses the vote should drink, if people tie they both drink, or if someone wants to volunteer as the question fits them then they should drink. Quick, simple, and fun the way a good night should away start.
To Start:
Give each player a player an numbered card or a piece of paper with their number written on it; this is how you will know how you're voting for. Now give everyone a set of cards with each player's number in it including their own. These will be how you vote, for the play that will drink.
Once all the players have something to ID who you will be voting for card or paper and a set of cards to vote with, select one player to read the "Most Likely to Drink" questions, and have them read the first question.
After the question has been read each player should select from their cards with the number of the player they think is best represented by the statements and lay the card face down in front of their self.
Once all of the players have voted, everyone may flip over their voting card. Now count the votes and check the VOTING section to find out who should drink.
