Backdoor Comedy made its way into the Dallas comedy scene in a manner as modest and circuitous as its name might suggest. Before it reached its current intimate space downtown in the Doubletree Hotel, owners (and comics themselves) Jan Norton and Linda Stogner put together showcases in no fewer than nine other locations, including a deli, a bowling alley, and a feed store. Today, weekends see a large rotating cast of regulars and occasional drop-ins by celebrity guests who have included David Spade and Kathleen Madigan.
