Materials needed: none
Object: Make your cellmate talk loudly/shout in church.
Game Play: When your cellmate is whispering to you, push in his belly. If the conditions are just right, his whisper will suddenly change to a shout, and he'll get in trouble (not you). You don't get any points, but you do get to slap yourself on the back for getting your cellmate in trouble.
History: My cousin was whispering to me during church when a little red man with horns and a pointed tail whispered into my other ear. So I reached over and pushed in my cousin's tummy, and he sounded something like, "Hey, Mike, whaaAAAAAAAH!"
Took me a while to stop laughing.
