5 second rule 

When one accidently drops food, not held in a container or wrapper, on the ground. The rule states that if you pick it up within 5 seconds, it won't be contaminated. There is also a '10 second rule' variation. Unfortunately, both rules are urban legends -- The speed with which you can pick the food article back up has no bearing on whether it may receive germs.

Person A: "Crap, dropped a cookie."
Person B: "5 second rule!!"
Person A scrambles to pick up food article
