The Boband Tom Show: The caller in the Mr. Obvious sketches. In one the caller thinks there is a "critter" in the pipes under his sink and when his wife turns on a light switch it makes it madder than anything. He even tried to get it out once. The sketch lives on this trope. Many either end with bodily injury or came close to it. Others include: Driving a boat down a ski slope (confusing water skiing and snow skiing), Driving with the car sun shade up (not making the connection of needing to remove it), and more.
