It brings in people who want to see a gay comic and keeps away the one that don't. I have been a comic since 1993 and have made a living since 1996. And its been great. The jokes are the same just different setups. It's not just straight to gay, but it's rich to poor, Jewish to Christian, men to women, part of the country, etc.
Every audience is different.
There is no gay club circuit or gay clubs, per se, but there are events and theater shows and gay nights. We are not out enough to have our own club. Anything that offends me I leave out. I try to take responsibility for what I say and be a good man. Not really, 'cause I am the headliner.
