Chubby Brown is the lowest common denominator of chav humour, supremely unfunny, a piece of leftover debris from the 70's popular lowgrade stuff that passed for comedy then, a consummate racist, misogynist & all-round piece of crap.
This isn't merely my opinion, it's a matter of fact. You simply wouldn't believe the depths he plumbs in extracting laughs from drunk chavs.
I believe he's had to tone his racist 'jokes' down now when live, because of legislation, but believe me, they're just as gross as his misogynist ones. Sheer simplistic filth from beginning to end. He makes Benny Hill look like Woody Allen.
Sample of his toned-down stuff:

Definitely don't watch this if you're easily offended.
