During a viewing of the show, each time such a documented phenomenon occurs, players drink a number of sips of their preferred alcoholic beverage equal to the numeric score. A non-alcoholic beverage of your choice may also be substituted.
This may be used in fiction to make fun of another work, or just to have an excuse for the characters to drink. In the former case, the characters may comment that anyone actually attempting the game would quickly end up stinking drunk, passed out, or in need of medical intervention.
