Prick. And mostly unfunny.
He is one of those comedians where I can't help feeling a bit guilty for finding him funny. He has got perfect timing and delivery and is very good at thinking on his feet. Technically he is a superb stand up comedian IMO, but a number of his jokes on the blind, paedophilia/child rape and female public figures who happens to be ugly etc. are in very poor taste. Generally I dislike people who claim to be progressive, but goes after weak groups. Mean comedy should be reserved for attacking the rich and powerful or people with objectively terrible views like Neo-Nazis.
