Pooping into the tank of a toilet, and taking the float out. This will make poopy water overflow from the toilet tank. The pure genious of this action is that most people almost always leave the bathroom while the tank is still filling.

The nerve sensor inside your rectum that causes you to feel an increasing urgency to poop the closer you get to a toilet. The proximity sensor is activated by an already present need to take a crap. Once in the vicinity of a restroom, your proximity sensor will alert you that you are running out of time to reach the toilet and drop your pants, or suffer the consequences...
