Some of the show's funniest scenes are the ones that capture the mundane amid the odd. In New York City, for example, Attell drops into a gay foot fetish club, where several men are gleefully rubbing one another's feet. Though many viewers may well find this behavior strange, what's weirdest is how boring the scene seems. Attell knows this, and he does a good job hitting a mix of oddly dull and quirkily fun locations. Drinking is a central part of the show, as Attell travels from bar to bar meeting intoxicated folks from all walks of life. What's appealing about Attell in these different situations is how democratically he approaches people, whether he's speaking to a leather-clad gay biker, a homeless man sorting trash, or a drunken party girl.
While Attell's sharp wit mixed with a dark silliness is enormously appealing to some, he's not for everybody. His comedy routines (bits of which begin each episode) are peppered with masturbation jokes, semi-sexist humor, blasphemy, and near constant references to drinking and drugs. Insomniac certainly isn't for kids, and even older teens and adults may be offended or shocked by some of Attell's humor.
