Stand-up comedy has to be one of the purest art forms. One person on a stage, armed only with their wits and their speed. How does someone do it? Why does someone do it?

Comedian JT Habersaat literally wrote the book on stand-up with his new "Doing Time- Comedians on Stage." The book is available July 8th from Jawbone Press. And for more info on JT, including tour dates, check out his website.
