Each week, Chris Addison is joined by three up-and-coming comics, who bring some things to "show" and "tell" the audience all about.

The items - whether they are topical, personal or completely random - are the launch pad for the comics to each perform a mini solo stand-up routine, "telling" the audience about their chosen item, and "showing" why it's rich comedy pickings.

The audience also bring their own personal - and sometimes peculiar - items, which Chris and his guests use as a launch pad for further sofa-based discussion.

Divided into three rounds, round one sees the guests bring in their personal show and tell items; in round two they reveal their "homework" show and tells (set by Chris before they appear on the show); and in the last round the audience get to share their own items and stories with fellow audience members, Chris and the guest comedians.

The comedy guests include Roisin Conaty, Chris Ramsey, Elis James, James Acaster, Maeve Higgins, Joe Wilkinson, Celia Pacquola, Josh Widdicombe, Susan Calman, Joe Lycett, Nick Helm and Tom Parry.
