Alan Davies has criticised stand-up shows like Live At The Apollo for removing the rough edges from comedians' performances and being "like a football match with every shot on target".
The QI star said heavily-edited shows made stand-up look easy. He said: "Those shows are wall-to-wall hits, there is not a duff gag or a missed line, anything remotely like an actual gig is removed.
"It's like a football match with every shot on target."
Alan is a judge on a new ITV1 series Show Me The Funny, which sees 10 comedians compete for a prize of £100,000, a national tour and a DVD deal.
The comics slug it out in a series of dates around the country, compered by Jason Manford, before a live final in front of 3,000 people at Hammersmith Apollo in west London.
They have to produce five minutes of new material each week to impress Alan, fellow judge and comedy critic Kate Copstick, and a series of guest judges including Jimmy Tarbuck, Johnny Vegas and Jo Brand.
Among the would-be comics are Alfie Moore, 47, a serving police officer from Scunthorpe, and former model 27-year-old Ellie Taylor. The first episode sees them trying to entertain an all-female crowd in Liverpool with later gigs in front of a group of Welsh rugby players and the Scots Guards in Catterick.
Copstick said: "People are calling it The X Factor for comics.
"But I think it's more like Masterchef for comics. Which I suppose makes Alan John Torode and me the irritating shouty one."
Show Me The Funny starts on ITV1 at 9pm on Monday July 18.
