What is 36 Hour Rule?
If a houseguest, squatter or friend has left any take-away within your fridge for 36 hours or longer then the food is fair game and is fully within the public domain.
Bob: Dude! Where the fuck is my kung pau?
Alice: Dunno. Where'd you leave it?
Bob: In the fridge
Alice: And it's not there anymore?!
Bob. Umm... No
Alice: Well, how long ago did you leave it there?
Bob: Last tuesday, I think
Alice: Dude; That was like 3-times-the-36-Hour-Rule ago
Bob: WTF is the "36 Hour Rule"?!!!
