Spicy Keychain 

A prank in which somebody heats up another person's keys in an oven, then gives their unsuspecting victim the hot keys, causing surprise and a temporary painful sensation.

My keys! My keys are red-hot! Sammy, you rat! You weren't using the oven to bake salads! You were heating up my keys to give me the ol' Spicy Keychain!
