I like Demitri (I always thought it was Dimitri? w/e) Martin... not as much as some others...
I like Dane Cook a bit too...
I like Steven Colbert and Jon Stewart a lot... (not stand up comics, but w/e)
As well as the 'Blue Collar' crew... Larry the Cable Guy, Jeff Foxworthy, Bill Engvall, Ron White...
I like standup in general, but those are the only names that come to mind.
