Class of kids in IT. 2 kids always up to no good. Menaced some kids for their passwords, logged in as them and sent something offensive to the printer. Repeatedly. Serious posh teacher, when he realises, gives a loud voiced lecture. Kids go back to work. Do it again sending 50 prints with the word WANKER A4 size. Teacher really blows a gasket. Gets everyone off the computers and sat on the tables in the middle of the class and shouts at them a lot. Holds up the printout saying how it wasn't funny. Get's everyone to shout progressively louder: WANKER!!!
