Scott has been told that if he wants to get into action movies he has to be able to take some pain. The best way for big producers to find this out is to have him naked, bent over, and his muscular rump given a good caning. If he complains then he won't make a good action movie star.
This makes perfect sense to the knucklehead and its great to watch his massive buttocks, with the little tuft of hair sprouting from his hole, getting a proper seeing-to.
