A game of bluff.
Highest card = Loser
Spread cards around on a table. Everyone picks a card. Without looking at it, stick it on your forehead so that everyone else can see the card that you have but you can't see it.
Then start with anybody(or card dealer) by betting that himself/herself doesn't have the highest card on his/her forehead by pouring more into the designated cup. A person can't pullout once the game has started but is allowed to change his/her card during his/her turn. When everybody is done with their turn, put down the cards on the table, faced up and the person with the highest valued card drinks all that is poured.
