Will Mars began his comedy career in 2009 and gained recognition for creating and producing Joke Thieves, a format he has presented at the Edinburgh Fringe since 2013. He has also worked in the US, appearing on Showtime at the Apollo and NBC's Trial by Laughter. In 2021, he received the Malcolm Hardee Cunning Stunt Award for launching the '(Some guy called) Dave Joke of the Fringe' in parody of the broadcaster Dave's backing of a similar contest. It was the only award handed out in that festival, much depleted by Covid.
