Three men were walking though hell with Satan one day when they entered a room full of clocks all moving at different speeds. Each clock had a name under it. Getting curious one man asks,"What are the clocks for Satan?"

"These are masturbation clocks," he replied. "They give us a clue as to how often someone masturbates."

Upon inspection, the first man finds his clock, and its going at a moderate rate. The second man looks and finds his clock, moving just a little bit faster than the first man's. The third man looks and looks but can't find his clock to save his life. Finally he asks," Satan, where the hell is my clock?!"

With a snickering look on his face, Satan replies,"We keep it in the office as a fan!!"
