In 2005 Kayvan Novak and Ed Tracy created Fonejacker, a prank call-based show as part of Comedy Lab for Channel 4. After the pilot, he was given a Christmas special and a six-part series, which began airing on July 5, 2007 on E4 and September 7, 2007 on Channel 4.

The show features a masked prank caller (Novak) who phones unsuspecting members of the public under various guises, in an attempt to confuse or wind-up the recipient. The audio is accompanied by on-screen imagery, consisting of pictures of people with their mouths moving in a similar style to Monty Python animations, or by undercover filming in which Novak is in a street calling a company nearby, usually from inside a public phone booth or from a rickshaw. Occasionally short videos with actors are used instead of images. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
