Get the beer booty mug.
When you fall into the whitewater and have to drink a full can of beer out of a booty (water shoe) because you were claimed as a swimmer. If you do not do this, the river Gods will curse you and you will be bound to swim again the next time you are on the river.
Carter flipped his boat in a class II rapid and has to drink a booty beer in front of all his friends so he wouldn't be cursed by the river Gods. Carter isn't very good at rafting.
