If the cafeteria has mint chocolate chip ice-cream, Rule 37 dictates that one must partake. NO EXCEPTIONS
A: "Oh man that was a good lunch...I am so full"
B: "Let's get out of here...But first, a sample of desserts."
A: "Not for me...too full"
B: "Oh shit! Mint Chocolate Chip! Rule 37!"
A: "Fucked"

37 Rule is exactly when Jimmy had no luck in life, no love found, no looks remained, no life stays and 37 years old is the trigger.
Hey what’s up ?

Sorry man I’m adapting to the 37 Rule from now on.
