Improvisor Dave Hill is our guest today on “ADD Comedy with Dave Razowsky,” and you’ll be hard-pressed to meet a more positive and upbeat improv teacher and performer. Dave was awarded the iO West “Teacher of the Year” honor in 2014, and it’s not surprising at all. He’s seen in numerous commercials, and shows on the tube including “Quick Draw” on Hulu and “Reno: 911” on Comedy Central. He’s a voice-actor, having worked on “American Dad,” “Squidbillies, and “The Most Popular Girls in School,” a great show both of us have recurring roles on, and one of the most “not safe for work” series on YouTube. There’s a very special story following the announcements, so be sure to stick around for it. By the way, the scratching sound you may hear are painters working on the apartment building. Enjoy Dave Hill!
