I saw dane cook about 3-4 years ago at carolines comedy club in nyc, he was actually really fucking funny(his comedy was new to me), and after he was done, he sat down and pretty much drank with whomever stopped by and said hi, so I'm pretty much a fan
Anyway, his comedy has nothing to do with political or sociological issues about our culture, besides even he did have shows about that, theres no way he can be as funny or revelant as colbert or stewart, so he rambles on and on about crap that could happen in everyday life(i.e. shitting on coats, grandma is a cheating whore), or nonsensical shit like putting your cashew on the tip of penis and shooting it in your mouth lke a sling shot, or smelly vaginas(which by far is the funniest to me)
It's extremely subjective humor, love it or hate it, I love it
