I've caught this pupil sniffing the girls shoes while they were in gym class, so I have sent him to my office till I come up with a suitable punishment. When I get to my office I make him strip naked and lay under my desk while I mark some papers. Once he's under my desk I smother his face my feet and then proceed to put my foot down his throat one after the other, and he just has to lay there and take it and can not acknowledge me while I finish my work.
