Philomena Cunk actually started as a "man-on-the-street" interview segment on Charlie Brooker's Weekly Wipe. She was often shown alongside Barry Shitpeas (whom I miss dearly). Philomena's character was quite popular however, and Brooker has written many spin-off shows featuring her, with titles styled like "Cunk on..." such as Cunk on Britain and Cunk on Earth.

If you recognize the name Charlie Brooker, it's more likely you recognize it from his show Black Mirror. I honestly quite like his comedy much better and think A Touch of Cloth is wildly underrated.
