Originating on Fox FM, it was broadcast nationally on the Hit Network from 2007 to 2010 in the weekday drive-time slot. The show was the highest-rated radio series in Australian history, consistently gaining up to 20% market share in the crucial Melbourne market, with around 2.7 million listeners and 1 million podcast downloads each week. The duo retired from the show at the end of 2017 before it returned in a weekly podcast-only format in 2018.

A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
