This game requires either an open space or a hallway wide enough to have two people move through.
Works best with large groups, divided into two equal teams. At one end of the hallway place either cups of beer or shots, then have a relay race with each person going down drinking their drink and coming back, to see which team can finish all their alcohol first. Each time you race change the style, ex: running backwards, crawling, spinning, hopping, eyes closed, and you can think of others.
Losers then each have to drink the amount that they lost by before moving onto the next round.
