I enjoyed his time on LCS, and felt he deserved to win that season. I've seen some of his stuff since, and it's funny... but he's falling in to the same routine as a lot of other stand-up comics. Let's see how offensive and shocking I can be? I'm not easily offended, but I don't think racism, sexism, foul language, and black humor is inherently funny. It's been done to death and you will entertain me more if you can make me laugh without trying to make me gasp in shock.
Just my two cents.
I recently discovered Reginald Hunter. Not particularly clean either, but he tells a good story.
