Bob Beshere¬†has been performing comedy since his senior year of high school, after his drama teacher volun-told him and his two nerdy friends they’d be performing an improv show with two pretty girls. The show went well enough for Bob to say, “All right, this seems fine.” Bob has been performing professional improv and sketch comedy for 20 years and even dipped his toes in the stand-up abyss. He is pleased to present his show “Powerpoints,” where a screen behind him will be doing all the heavy lifting.
