Who Said That? is a comedy panel show hosted by Mark Olver. Each episode sees four famous faces dial in to test their knowledge of how each other thinks and make each other laugh. Guests include James Acaster, Jon Richardson, Rachel Parris, Kerry Godliman, Jen Brister, Mark Watson, Russell Howard, Richard Osman and many many more. The game is simple - each round, one player asks a question which the other three must answer. They text their answers to Mark who reads each one out. The questioner then receives a point for every answer they pair correctly with an answerer.
