One Question
8pm, Channel 4
“What happened in 2000?” That’s the one question Claudia Winkleman has for 999 call operators Shiralee and Emma tonight. If they get it right, they walk away with a big cash prize. It should be the “easiest way of winning £100,000”, says the always charismatic and heavily fringed Winkleman – but with 20 possible answers to choose from, it’s much trickier than it seems. This new quizshow could have what it takes to become a Friday-night fixture. Hollie Richardson
Gardeners’ World

Young Rock
8pm, Sky Comedy
Another double bill of likable shenanigans with Dwayne Johnson’s child alter ego. First, a wrestling grudge match and a stolen ladder land our little man in trouble in Hawaii in 1984; then, three years later, muscly 15-year-old Dwayne has to fend off Nashville’s randy housewives. Jack Seale
This Is MY House
8.30pm, BBC One
Who really owns a nine-bedroom Georgian mansion house, complete with a broken window that was caused by a flying potato? Judi Love, Richard Madeley, Harry Hill and Mist are the celebrities tasked with identifying its owner. HR
Avoidance
9.30pm, BBC One
Claire and Spencer are having a mystery man named Steve over for dinner – sending Jonathan into a jealous tailspin: “Steve is making Claire a curry! Am I overreacting?” Meanwhile, Courtney’s date night could, frankly, be going better. This perfectly pitched comedy of (bad) manners and regrets continues to break your heart, ever so gently. Ali Catterall
The Lateish Show with Mo Gilligan
10pm, Channel 4
The Bafta-winning show that brings a touch of cheerful chaos to the variety format continues. Alongside Gilligan’s mixture of sketches, games and music (Tom Grennan performs), guests include new Dragon Steven Bartlett and edge-walking, comedy renegade Joe Lycett. Phil Harrison
Film choice
House of Whipcord (Pete Walker, 1974), 11pm, Talking Pictures TV
Any movie that opens with the words “This film is dedicated to those who are disturbed by today’s lax moral codes and who eagerly await the return of corporal and capital punishment” will have an uphill battle on its hands, but this campy low-budget 1970s British horror – about an old judge who runs a brutal correctional facility from his mansion – is cheap and nasty in all the right ways, if you like that sort of thing. Hard to watch at times, it is the sort of grubby mess that sticks with you long after it finishes. Keep your eyes peeled for a young Celia Imrie, too. Stuart Heritage
