Elliot:
Okay here's what FO REALZ happened and you can submit this to Myth Busters, the Oracle of Delphi, or any other Higher Power. One night [REDACTED] was going to bed and instead of just taking off his pants and shirt and going to bed he took off his pants AND underwear accidently. Hasn't that happened to you sometimes? Sure. Okay so he gets into bed and he's like "OH MY GOD MY GENITALS ARE EXPOSED" and goes back to put on his underwear he just removed accidently. He puts his underwear on...but being both tired and annoyed they accidently go on backwards. Having no real purpose for the Manhole to be on the correct side, his mistake goes unnoticed.
Elliot:
During the night he receives a txt message or his battery life on his cellphone goes down a notch or something and he sees a flashing light.
