A boat race (Beer On A Table Race), is a drinking game between (usually) two teams of equal numbers. Rules vary widely but normally involve a team drinking in series and aiming to finish first. Common rules include those regulating the number and gender of drinkers, the vessels from which the liquid must be consumed and punishments for spilling. The game appeared in the Broken Lizard movie Beerfest.
A race begins with all competitors placing their drinks on a mutual table. When a referee begins the race, the first drinker on each team is allowed to pick up their drink and begin drinking. Once a beverage is consumed, the drinker must invert the empty vessel on their head. This is done to ensure no cheating occurs. The next team mate cannot touch his or her drink until this has occurred. Empty vessels must be kept on the competitors head until the race is over.
