When you were a kid and dropped some precious candy on the ground, you thought nothing of quickly picking it up, dusting it off and putting it back in the ol' candy-hole. As long as you shouted "five-second rule!" before doing so, you were good to go. As you got older and wiser, you dismissed this rule, but the scientists from Discovery Science Channel's "The Quick and the Curious" show say you weren't as dumb as you thought. To prove this point, NASA engineer Mike Meacham goes around the park offering free chocolate chip cookies to everyone, with one catch—he drops it on the ground first. Most people decline, but one smart/hungry man isn't about to pass up a free dessert. "God made dirt, and dirt don't hurt" he said. Can you blame him? His girlfriend did.
