"The preferred method of sleeping arrangements wherein two heterosexual men are forced to share a bed for a night. Both men are to strip completely nude and sleep facing apart, with their anuses touching. Throughout the night, the two men must defecate, and in turn, redefecate into each others' anuses, transferring the waste between themselves. By staying in this position throughout the entire night, they will have proven their heterosexuality, and cannot be subject of ridicule regarding their sexual preference.
"If you're not gay, then you will follow Noller's Rules"
