The pair are currently writing the scripts for Bigipedia, described as 'a malevolent mix between Google. Microsoft and Wikipedia'.
Kirshen says he finds the 12-hour days preparing for the show gruelling, writing on his Twitter page: 'If I'd worked this hard at uni I wouldn't be in comedy.'
Doody has previously described the series as 'a piss-take of Wikipedia, with all the same inaccuracies, written by nutters'.
The show will be recorded from this week, and go out in late July. It was commissioned from independent production house Pozzitive following a successful pilot last year.
