Mark Rosenthal is a 2-time award winning karaoke singer and 0-time award winning comedian based in Chicago. He’s not so much a stand up as he is a man teetering on the edge of madness (and yelling) about his life experiences with hyperbolic absurdity. Plus he does goofy songs. His writing/producing credits include BLOODSPORT! The Musical, Escape From Chicago, My Brain Is Broken, and AMpocalypse. He also co-hosted the open mic/showcase Get Up, Stand Up. However, you least likely remember him as O’Brien from the very end of the Chicago PD episode “Little Bit Of Light.” Like all late-30’s bearded white men, he has a podcast nobody listens to, called Body Counts and Beer, available wherever you get podcasts from. Even Spotify.
