We begin with a quiz to decide who goes to The Human Carwash (loser of the quiz) and who goes to the gunge tank (winner of the quiz). The loser will face The Human Carwash getting a gunging and total drenching. However, at the end of the ride, 2 levers await the soggy contestant. One of the levers will release the final gunge pump all over them, but the other is attached to the gunge tank perched above their opponents. So, although they are covered in gunge, there is the chance of a slight bit of revenge at least.
