The producers explain: "Bring It On is a hilarious new format with a very simple premise: every member of the audience must bring something along to the recording.
"Showcasing everything from regrettable impulse buys to embarrassing family photos, inappropriate gifts to toe curling teenage love letters or even baffling family heirlooms to hideous items of clothing, the format combines the curiosity of Antiques Roadshow with the spontaneous wit of Mock The Week. There'll even be a cash prize for the best item on the night!"
It is believed the pilot is aimed at TV, although no channel has been revealed yet.

Below is a picture from the filming which took place earlier this month:
