Whack-O!, a British sitcom TV series starring Jimmy Edwards, was written by Frank Muir and Denis Norden, and broadcast from 1956 to 1960 and 1971 to 1972.

The series (in black and white) ran on the BBC from 1956 to 1960 and (in colour) from 1971 to 1972. Edwards took the part of Professor James Edwards, M.A., the drunken, gambling, devious, cane-swishing headmaster who tyrannised staff and children at Chiselbury public school (described in the opening titles as "for the sons of Gentlefolk"). The Edwards character bore more than a passing resemblance to Sergeant Bilko as he tried to swindle the children out of their pocket money to finance his many schemes.

The first six episodes were subtitled "Six of the Best". In 1959 a film was made based on the show, called Bottoms Up!. The series was revived in colour with updated scripts in 1971–72, slightly retitled Whacko!. In all, it ran for a total of 60 episodes, with 47 of black-and-white and 13 colour, of 30 minutes each. There were three special shorts. There was also a radio version with Vera Lynn starring as herself in the second episode. Many of these radio episodes were recovered by a BBC archivist from a listener's collection of tapes in 2012.

The front of the historic house of Great Fosters near Egham in Surrey was used in the opening title sequence of the TV comedy series, behind the name of the fictional Chiselbury School.^[1]

Theme of school corporal punishment

TV comedy historians have written that the central theme of Whack-O! and Bottoms Up! was corporal punishment and specifically the caning of boys’ backsides. This however was largely absent from the revived series in 1971, as by that time corporal punishment was becoming less acceptable in Britain and was eventually banned in state and many independent schools in 1986.

Whack-O! tended to glorify a ritualised form of punishment that had been an accepted practice in British schools, but by modern standards the popular humourizing of corporal punishment is an anathema, and it may seem somewhat perverted in the way it was featured in the series. The comedy of the series was built around whether boys would be caught and punished for minor misdemeanours, and the size and effectiveness of canes and the building of caning devices. In one episode a device and long cane was made so six boys could be punished together. In another a device was made so the teacher carrying out the caning did not see the boy, and it turned out that all the backside seen to be caned were that of deputy headmaster Pettigrew (when played by Arthur Howard). A feature of Edwards carrying out punishment was the clear enjoyment he exhibited.

Both Jimmy Edwards and Arthur Howard were gay men and Anthony Slide, a biographer of Edwards with "Wake Up at the Back There! It’s Jimmy Edwards (BearManor, 2018)", has written: "I know I’m a little perverse, but I cannot find it anything but fascinating and decidedly weird that two gay men were starring in a BBC series involving the use of a cane on the bottoms of young boys."

• [1] Biographer of Jimmy Edwards

This is how the BBC sums up this aspect of Whack-O! on its official website: "Watching the series now is a little painful in one respect – we're too sensitive to find canings amusing – but it's right on the money in other ways, mainly because finding over-privileged kids vile hasn't gone out of fashion."

Details of radio adaptation

BBC Radio adapted the TV scripts into 45 thirty-minute shows, mostly with the original cast, of which 42 recordings survive. There were three series which originally ran on the BBC Light Programme from 23 May 1961 until 22 July 1963. They have been repeated on BBC Radio Extra since 2015 and the last airing was in 2020.
