Someone once said to the loathsome Bernard Manning at a gig 'Manning You fat c*nt!
His put down was - "Correction - rich fat c*nt"
I love stand up comedy and have seen several live shows including Newman & Baddiel, Jack Dee and Jasper Carrott. My favourite at the moment is Eddie Izzard but for put-downs I think that women such as Jo Brand are funniest.
