"You know why your're here?" asked Jeremy Clarkson.

"Somebody else dropped out?" snapped back Jimmy Carr as he settled into the seat on Who Wants To Be A Millionaire? and Clarkson made a joke about the late Sean Lock – "they were promised Sean Lock".

"Jimmy Carr and your new hair, let's play Who Wants To Be A Millionaire?"

He guessed the answer "G&T" to the first question before it came up. Could he be too confident? He admitted to being cocky on the first one.

"Lips are..." "Sealed" - the second question was a doddle.

Boy's name used in radio communications to confirm message received? "Roger" - said the Roger Federer lookalike.

Which Warner Bros character is an amorous skunk? "Pepe Le Pew" But he did have to work through the options...

He got to £1000 by knowing UCAS was universities before the answer came up.

"You're not here to win money for yourself" "What?" He joked if he wins a million pounds can he give some of it. He checked it was tax free just in case...

He jumped in quickly to show that he knew Garra Rufa fish were used to treat feet. £2000 in the bank.

He knew what "bunny boiler" was too - Fatal Attraction.

Latin word for elsewhere? "Alibi" "Nice work," said Clarkson.

"Out of the strong came forth sweetness" is the slogan on what? The first question that stumped him and he asked the host. Amazingly Clarkson used to have golden syrup on his porridge and knew it. 

On Twitter though some people thought Carr was a bit too confident. " Jimmy Carr is acting like a dick, wondering he has taken." "No faffing or stalling by @JimmyCarr - he's romping along!""Jimmy Carr is awffy cheery on #wwtbam" "Jimmy Carr on millionaire is just an annoying fucker."

Atmosphere of Mars got him thinking. He thought it was carbon dioxide but decided to phone his friend who thought it was nitrogen but not certain...50/50 knocked out nitrogen, Carr went for another phone a friend. They said carbon dioxide, he went for it and got it right.

Having lost all of his lifelines he set his safety net at £64,000. He needed to know 1938 record breaking steam train and didn't know. He went for Flying Scotsman. He was wrong, it was The Mallard. He lost £31,000 and left with £1000.

Viewers didn't seem very generous. "How did @jimmycarr not know it was The bloody Mallard.""you absolute bell end ! Wasted 3 lives and didn’t even know the Mallard." "Jimmy Carr new t.v show...8 out of 10 cats does steam trains "
