So three men are drinking in a car. They get pulled over by a female cop, who comes up to the side window. They roll down the window, and she says "I’ll let you three go free if you all together add up to 21 inches." So the driver pulls his pants down. 10 inches. The man in the passenger seat pulls his pants down. 10 inches. The man in the back seat pulls his pants down, and he’s only one measly inch. However, they do in fact add up to 21 inches so they get to go free. As they’re driving down the road the man with the one inch dick says "THANK GOD I POPPED A BONER BACK THERE GUYS!!!!"
