The first accident known in Ispog was Robert Buckeridge's fall from the black pole, due to him wearing his school bag too loose on one shoulder. This meant he never pole-slided again. (Or should that be pole-slid?)
Timothy has had the largest number of Gopsi accidents, including falling off the pole more than once, falling flat on his face while running in to the common room and having a rather larger accident by an evil woman.
Other Gopsians are noted for their accidents, for instance Stephen falling down the Ispog steps and tearing his trousers; and David, who, having miraculously surviving Timothy's accident unharmed, went over the handlebars on his bike.
