[2] The first series was hosted by Patrick Kielty, with regular performers Jack Whitehall, Kevin Bridges, Andi Osho and Rich Hall.

Bridges replaced Kielty as host for the second series, with Jon Richardson joining as a regular performer.

[3] Richardson took over as host of the show for the third series which aired in late 2011, and aside from Rich Hall returning, an otherwise entirely new group of regular performers joined the show: Seann Walsh, Sara Pascoe, Josh Widdicombe and Paul Chowdhry.

[8] The first series also featured a segment called "The Chair", in which a celebrity guest sat through a two-minute comedy routine about themselves from Kielty, after which they had 30 seconds to talk about or defend themselves.

[9] The first two series were recorded at KOKO in Camden, London, in front of a live audience.
