Oh, I just read you are a stalinistic snob... 😉
And to be honest: the guy has a lot of fans who come to hear his jokes and laugh... You're entitled to not like his jokes of course. But I do have to take his side to the very simple premise that a comedian should make his audience laugh and unless they indeed CGI'd the audience and used fake laughs, he does do just that.
In the US there was this funny reality/competition show like America's Next Top Model): Last Comic Standing. The only way to win was, in the end, to make the audience like you more than the one you were battling. I think colleagues bashing him is a bit lame and cheap.
Audiences not liking him: don't go to see him, don't buy his DVD's, don't watch the show.
