Passed along, with the following email, from Megan (thanks!):
This guy has very thin walls and everytime his roommate has sex with his girlfriend, he does a challenge. The goal is for him to complete the challenge before the couple finishes having sex. If he doesn't, he does some silly punishment for himself (eating wasabi, finger in a mousetrap, etc). It is HILARIOUS, I literally laugh out loud every time.
See the rest of his challenges here.
