Mark Olver is a central figure in Bristol's stand-up comedy scene. He has worked with everyone in the industry - from long-term friend, Russell Howard, to Flight of The Conchords. Mark's series of "Belly Laughs" events raises money for a homeless charity, while his recently launched online comedy panel show "Who said that?" has proved that Zoom meetings can be funny. We chatted about the south west's comedy scene,  collaboration amongst comedians, and how to deal with the repetition of doing TV warm-up.
