GEOFF BOLT To Geoff comedy is a serious business. He is a master improviser, and a liar. Over the years Geoff has done more than 1000 voices for video games and radio and TV commercials. He has appeared on every major TV network and headlined in comedy clubs across the country. He can also be seen in several feature films and even a couple of documentaries. He is one half of the podcast O'Brien & Bolt heard wherever podcasts are heard, and he is a regular guest on NPR.
