My friend told me about the show and I finished watching all 5 seasons in 1 week. =P It's hilarious to say the least. The characters are akin Seinfeld's due to their complete lack of moral fiber. Most of the comedy revolves around their chaotic lifestyles and the trouble they get into from making very poor decisions.
They did an episode where Mac and Dennis try to pitch a product to some merchandising convention. Their product is the Dick Towel, which Mac makes a website for. The website turned out to be real and I found their commercial there

Anyone else watch it?
