Whacko! - Full episode

Starred 'Professor' Jimmy Edwards as the conniving, cane-thrashing, horse-betting (and often drunken) Headmaster of Chiselbury School ('For the Sons of Gentlefolk') with his assistants Mr. Oliver Pettigrew, the science master, played by Arthur Howard who was also his long suffering assistant headmaster...a twittering, hand-wringing bag of nerves. Mr. Halliforth was played by Edwin Apps. Also appearing was Gordon Phillott as Mr. Dinwiddie who was very ancient and deaf. The headmaster was always dreaming up schemes to make money for his beer fund and thwacking young boys on the behind with his faithful old cane. Especially a boy called Wendover. Hence Jim's favourite instruction to the boy: "Bend over, Wendover!"
