Made in Chelsea cast, Alan Carr, Kirstie Allsopp and Channel 4 News team among the celebrities taking part in special night
It began in an age when crafting a special mixtape was a popular way to impress a loved one.
So it seems appropriate that Channel 4 is kicking off the celebrations to mark 30 years since its launch by effectively putting together a televisual mixtape for its viewers.
The Channel 4 Mash Up on Monday night will see some of the broadcaster's biggest personalities appear in one another's programmes
The comedian Alan Carr will join Kirstie Allsopp poking around other peoples' houses and being cross with buyers when they don't do exactly as she tells them.
The Made in Chelsea cast will pause the "highly annoying" button for about a second as they attempt Come Dine With Me without caterers, butlers or any of the other ludicrous services they would usually employ – in between their important shopping trips and endless discussions of friendships and relationships behind each others backs.
Meanwhile, the teams from 8 out of 10 Cats will swap their comedy answers for nimble letter-arranging and the fiendish number round on Countdown, and the Channel 4 News presenters will attempt to give Hugh Fearnley-Whittingstall a run for his money as they take over the River Cottage kitchen.
Recalling the experience, Jon Snow said: "I cannot believe I skinned a rabbit. I cannot believe I ate that rabbit.
"I learnt more about foraging from a few hours with Hugh than I have learnt about the euro in a decade. He warned me that the long thorns that surround sloe berries may inflict a wound upon you that will go septic. I have the wounds. I'm still waiting …"
Snow is actually quite squeamish about blood and guts, said fellow newsreader Krishnan Guru-Murthy.
Another colleague, Cathy Newman, said: "Turning hunter-gatherer for the weekend must surely come in useful for my day job. Slicing into a rabbit? Skewering a crab? Politicians coming into the studio for interview should know I'm now ready for anything."
