Alcoholics Anonymous is spiritual, not religious. You can pick anything you want to be your higher power, even a door knob.

A farting game. When someone farts who is playing the game, he/she must say "safety" before another participant says "doorknobs." If "doorknobs" is spoke before "safety," the farter can be punched in the shoulder unless said farter touches a doorknob. When played by veterans, the pre-fart safety, "pre-safety," can be employed for no more than two minutes to allow for those times of uncertain gastric distress.
Me: <fart>
Other: "Doorknobs!"
Me: Moves toward closest doorknob too slowly.
Other: <smacks me in the shoulder hard>
Both: Laugh.
