This British sitcom was one of several TV vehicles for mustachioed comedian
Jimmy Edwards. On this occasion, the star was billed as Professor James Edwards, the headmaster of Chiselbury School. A stickler for discipline and protocol, Edwards was invariably undermined by his own stupidity. Originally telecast from 1956 to 1960, toting up 60 episodes in the process, Whack-O! was revived for an additional 13 installments in 1971. The series also spawned a theatrical feature,
Bottoms Up (1960). ~ Hal Erickson, All Movie Guide
