On Bill sneaking out to perform comedy
>"It has become one of the more famous bits of Bill Hicks lore, that he used to sneak out of his house as a teen to go perform stand-up comedy in nightclubs. It's true. I ran the getaway car. Aiding and abetting."__________
On Bill and Dwight's first stand-up gig together
>"They'd been working on their set list in Bill's room all week, and they had decided to go mostly with one-liners about their inability to get women. 'We were sexually abused when we were younger...' Bill said. 'Yeah, we never got any,' Dwight finished. [...] To their delight, they were killing. If people weren't necessarily responding to the jokes themselves, the sight of these two awkward kids talking about sex was enough."__________
