Ron White. I find him very offensive and a drunk.
The only 2 that even come close to funny is Ellen Degeneres and Alan Carr in my opinion. the rest are just blahh.
But overall, I don't think any of them are funny. maybe its just not my type of humor.
Chris rock, Carlos Mencia, Adam Sandler, Ken Jeong... I'm sure there's more but they're just not funny enough to remember.
As for Comedians I do like. Don Rickles, Norm Macdonald, Louis CK, Seth Myers,
Neil Patrick Harris
