8 Out of 10 Cats Does Countdown - Season 28 Episode 1 Bob Mortimer, Tom Allen, Richard Ayoade, Harriet Dyer & Ian Smith
7.30 47 minutes Jimmy Carr returns with a brand-new series of the chaotic comedy twist on Channel 4's classic words and numbers quiz. In this episode, Richard Ayoade and Harriet Dyer take on Bob Mortimer and Tom Allen. Ian Smith's in Dictionary Corner with legendary lexicographer Susie Dent, while maths machine Rachel Riley looks after the numbers. And Joe Wilkinson - quite literally - drops in. Because of course he does.
