On Last One Laughing, the comics are given six hours to make their opponents giggle.
Laugh or smile once, and you get a yellow card from host Jimmy Carr.
If you break twice, it’s a red card and you’re out.
Maisie says the atmosphere is a bit like being at school at the back of the classroom.
“You’re not meant to be laughing, but you can see all your mates trying to make you laugh, and they’ve got that twinkle in their eye,” she says.
“You see them trying to stifle a laugh. It’s that, for hours on end.”
Maisie’s rivals this series include comedians Diane Morgan, Mel Giedroyc and Romesh Ranganathan.
But she was most nervous about facing returning champion Bob Mortimer, who entered season two to a chorus of dismayed gasps.
Maisie says: “When we were doing our interviews beforehand, they were asking: ‘Who would be your worst nightmare?’
“And we said Bob Mortimer, but thankfully he won’t be in.
“He smashed it in season one, and because he was on season one none of us thought he’d be in this one.”
Maisie says Celebrity Traitors winner Alan Carr was also a fearsome opponent.
“Anybody who saw Alan in the Traitors knows he’s completely unserious,” she says.
“He’s funny before he even opens his mouth because of the looks he’s giving.”
