yes they are...
Chapelle's Show is funny to be sure, but Mind of Mencia is funnier on a pure comedy level. That and I don't know if Dave Chapelle really wants to do that anymore anyway.
I like Chappelle's Show a little more than Mind of Mencia. While both play heavily on racial matters (and are very funny about it), Mencia needs to use a thesaurus, because I can only heard "beaner" so many times before it loses its comedic punch. he uses it EVERY TIME. ya know?
I first saw Carlos Mencia on Comedy Central almost 10 years ago and he had me in tears I was laughing so hard. His show is sort of an extension of his live comedy acts, which I've been to see in person.
He's not conservative, he's not liberal, he's just a guy who I think is the best comedian out there since Sam Kinison.
I grew tired of Chappelle's cheap race humor by episode 2..... Highly overrated. South Park is still the yard stick against which any show on Comedy Central must be judged.
