As well as giving rise to [[The Goodies]] team, ISIRTA shows the roots of the [[Monty Python]] team very clearly, with Cleese, Chapman and Eric Idle all regular script contributors. The show's creator Humphrey Barclay went on to create the TV show ''[[Do Not Adjust Your Set]]'', featuring the rest of the Python team, as well as Idle.

''ISIRTA''{{'}}s roots can be traced back to classic radio comedies like ''[[It's That Man Again]]'' and ''[[The Goon Show]]''. As with ''[[Round the Horne]]'', the cast's adventures would sometimes be episodic with cliff-hanger endings each week as with "The Curse of the Flying Wombat" (3rd series), and "Professor Prune And The Electric Time Trousers" (7th series). Christmas specials normally included a spoof of a traditional [[pantomime]] (or several combined). They had few qualms about the use of puns – old, strained or inventive – and included some jokes and catchphrases now considered politically incorrect. Garden's impressions of the rugby league commentator [[Eddie Waring]] and the Scottish TV presenter [[Fyfe Robertson]], Oddie's frequent parodies of the game-show host [[Hughie Green]], and Cleese's occasional but manic impressions of [[Patrick Moore]] (astronomer and broadcaster) also featured.

As the only woman on the show, Jo Kendall voiced all the female characters (with the exception of Brooke-Taylor's oversexed harridan, Lady Constance de Coverlet) and occasionally extended into having conversations with herself in different voices. (In one episode of the serial "The Curse of the Flying Wombat", not only did Kendall play two characters in the same scene but so did Tim Brooke-Taylor, resulting in a four way conversation between the two actors). Kendall also wrote some of her own material.

The show ended with an unchanging sign-off song, which Bill Oddie performed as "Angus Prune" and was referred to by the announcer as "The Angus Prune Tune". Spoof dramas were billed as Prune Playhouse and many parodies of commercial radio were badged as Radio Prune.
