If an argument concerning the rules is going on (2 players, a player arguing in the face of a GM ruling, etc.) and it begins to bore any person at the table or watching the game, that party may call Shenanigans.
When Shenanigans is called, a stopwatch or timer is started. Parties involved in the dispute have 3 minutes to state their case and come to a mutual agreement. After that, the decision is made randomly. The decision of the dice must be obeyed, even if someone believes it directly contradicts the official rules.
If a party is painfully aggrieved by a decision made during the game, s/he will receive a "playing in protest" coupon for a metagame reward after the game at the expense of the other players--usually in the form of beer, ice cream or shots of Jager in whatever quantities will get him/her to shut up and roll. However, thereafter the other players are entitled to mock the player during the next session (only), though the rate must be no higher than a single one-liner per player.
A version of these shenanigans rules has been added to Gigacrawler.
