People never ceased to ask you, in more and more obscure terms, whether you had a penis or a vagina. The idea was to catch the person out, and then taunt them interminably until you thought of something more personal and embarrassing to ask them about. We soon moved on from Pencil/Sharpener to Spaceships/Space, and Lorries/Roads. It was a Christian school, they weren't about to inform us of how far out our ideas about genitalia were. Instead Mr. fucking savage would come and dance about like a moron with songs about the cool cat from Galilee every Wednesday.
