Welcome to the Dumb John Website

American Style Improv from Chicago, Illinois.

Regarded as "one of Chicago's funniest and most promising improv groups of the last decade,” Dumb John is proud to return to The iO Theater, where they got their start; with a new weekly long form improv show. Longtime members Katie McClain, Mike Geraghty, Steve Plock, and Linda Orr apply their high energy strain of improvisation to a bizarre cultural harvest of small town Americana influence and ephemera. Dumb John uses a single audience suggestion to inspire a piece of unhinged long form improv that propels diesel-soaked characters through fever dream karaoke scenes and down neon aisles of roadside antique marts; exploring the depravity and brilliance found at the heart of every moment. Wipe off your boots, grab an ice cold cruiser, and join them for an evening of more fun than the law allows.

Dumb John is an improv group that has been performing for over 10 years all over the world. They perform weekly in Chicago and have performed all over the world in places like Iowa City, Naperville, Iowa City, and Vancouver.

People on the Improv subreddit contend that Dumb John is one of the best improv groups in Chicago "right now".
