Car Muffler Exhaust Whistle Prank by Joker($4.99Value)

Description

This classic prank has been around for generations, but it still works today. You simply place this little metal tip on the exhaust pipe of someone's car. When they drive down the road the tip causes the car to whistle while they are pressing on the gas pedal. The whistle becomes so annoying after a few minutes, but the poor sucker has no idea where it is coming from.
