Comedian Steve Byrne must have a lot of fun filling out census forms. Having sprung forth from the union of an Irish father and a Korean mother, he describes himself as a "CaucAsian," meaning his brand of humor must lie somewhere in the comedy gulf between Margaret Cho and Colin Quinnâthe latter of which he accompanied on USO tours of Iraq and Afghanistan. (As John Kerry might say, "Educationâif you make the most of it and you study hardâ¦you can do well. If you don't, you get stuck listening to Colin Quinn.") Catch the "CaucAsian" Wednesday through November 19 at the Improv, 4980 Belt Line Road in Addison. Call 972-404-8501 or visit improv.com.
