Well I don't find what you call, "Stupid Comedy" very appealing. It's lazy, and anyone can look like a moron. If you want someone that's good at being mentally disabled, then just stick a video camera in a special ed classroom.
I also think racial humor is incredibly overrated.
I do enjoy Ron White. I really like mostly quiet mono tone comedians, that can keep a straight face the whole time, and be hilarious, or even look depressed.
I find that to be very talented, and incredibly funny.
Larry the Cable Guy...I just don't like Larry the Cable guy.
Jeff Dunham is very talented.
I dislike that Pimp guy.
Oh a comedian that is also decent is, Cathy Griffin.
