Heckler vs Jimmy Carr in Stoke on trent a few years ago.
At some point in most of his acts (we've seen him on several tours at this venue) he usually asks the audience to ask him questions. This time, after a few of the usual questions that Jimmy has an witty, smug or fantastically offensive answer to, this weirdo stands up and asks,"Why did you sue your father and get him arrested?"

There was a deathly silence from the audience followed by some confused titters as Carr stood silent, his face then cracking into rage rather than humour. He beckoned security and the guy was escorted out of the room.

Before they had left the room though, Jimmy called them back, apologised to the man for his knee-jerk response and said he could stay saying that anyone who pays 30 quid to embarrass him was welcome and he'd enjoy spending his £30 a little bit more than the rest. Which broke the tension and got things rolling again.

Sorry for lack of funnies but it was probably one of the best and worst heckles I've ever heard (mis)handled by a professional comedian.

Talking of Mr Carr,
Saw him at Ipswich Regent and he was mid flow when some douche bag shouted out " Your a cunt". Jimmy just stopped and said "well you paid thirty quid to watch me so who is the cunt now". Was one of those pure genius comedy moments that bought the house down...

At least he MTFU pretty sharpish.
It takes a certain amount of guts to publicly apologise for reacting so divarishly.
