Backwards writing
My old science teacher used to always lean against the same desk, in exactly the same place, at the back of the class.

Me and my mate Peter had the idea of backwards writing in thick chalk on the edge of the desk that he would lean on, and we could not have hoped for it to work as well as it did, so every week for three years we managed to get a message printed onto his arse, starting with mature things like "I'm gay" or "I lilke little boys" but moving towards self referential "I am a message on your bum" to serialised "you will never catch us", over a five week period.

On our last day, Peter, me and a later recruit Vikesh confessed all and to be fair to him, he shook us by the hand and said he had taken it in good fun, but had had no idea how the fuck kids had managed to write on his arse without him noticing.
