Hannah and Verity each have a box, one of them contains a pie, the other is empty. Hannah will look inside her box to see if she has the pie and try to convince Verity whether or not she should swap or not. The person who ends up with the pie in the box, gets the pit (in their face) and a trip through The Human Carwash. However, at the end of the ride, 2 ropes hang down, one of the ropes is connected to the final tank in the carwash, the other is connected to the gunge tank occupied by the winning opponent. The person in the carwash does not know which is which, but is only allowed to pull on one of them.
