How far are you willing to stretch 'reality show'? I imagine the Celebrity Bake Off with Joe Wilkinson where he bakes a cake of his arse would be fun. Well, I'd recommend anything with Joe Wilkinson (he's often on 8 Out of 10 Cats Does Countdown - his poem 'Hanging About In A Train Station Toilet Naming People's Penises' will make me laugh every time I watch it) or his sometime comic partner Diane Morgan. She plays Philomena Cunk and her part is scripted but some of the people she interviews aren't in on the joke. Some like Neil Oliver and Kate Williams who are in the industry obviously are or catch on quickly but some are confused and one guy clearly wanted to kill her.
I think there was a question about stand-up earlier - I'll put in a word for Dara Ó Briain, Jimmy Carr, Bill Bailey, Sean Locke, Lee Mack, the four-part James Acaster Netflix special.
Also Laura Solon's Talking and Not Talking radio series. And Dougal and Hamish: You'll Have Had Your Tea by Graeme Garden & Barry Cryer with Alison Steadman and Jeremy Hardy.
Sitcoms: Derry Girls, Detectorists (for a more wistful mood. Probably the my favourite series ending.), Toast of London, Black Books, The IT Crowd, Father Ted, The Mighty Boosh, Moone Boy.
