Rory Bremner has joked that quiz show contestants are "a different breed", describing them as "very serious" and "very funny".
Bremner's first ever quiz show, new Channel 4 daytime series Face The Clock, started this week and the TV impressionist said that he had loved the experience.
"They're a different breed quiz show contestants. They are called quizzers - they are very funny, they are competitive as a race and very, very serious," he told Digital Spy.
"Early on with Face the Clock, the quizzers identify who their rivals are and try to get rid of them. Those rivalries do develop on the show and we do get episodes where we get these people going at each other.
"There was also a great spat, where a woman revealed that she'd been married four times and the contestant next to them said, 'Some of these rounds have lasted longer than your marriages'."
The show, which Bremner claimed was "filmed in a shed just outside Dumbarton" ("It was one of the weirder locations I've ever worked in. It was an old whiskey warehouse"), features contestants tackling general knowledge questions with a time limit.
"The twist is that they don't know how long the round will last and I don't know how long the round will last and come the end of the round, whoever is still answering the question gets eliminated," said Bremner. "It's like musical chairs - you don't know when the music is going to stop.
"We had some great contestants. Some people would really know their stuff. We also had one bloke, who was my favourite, who didn't know anything. You'd ask, 'Who won the world cup in 1966?' and he'd say, 'Oh no!'
"The best bit was that he worked in counter terrorism. He said, 'Nobody knows anything in counter terrorism, but you're all safe, don't worry'."
