First you put the shot glass in the very large glass and then set up the smaller glass in front of the big glass. Fill the smaller glass half way full. If you make the quarter in the smaller glass you have to drink it. If you make the quarter in the large glass without it going in the shot glass, you can give it to anyone you want. If the quarter happens to go in the shot glass then you fill the smaller glass all the way up and give it to anyone you want. You play this game for an hour and you are guaranteed to be fucked up. The best Ultimate Quarters drink you've ever drank!
