I realise this says more about me, but my instinctive response to hearing about a real-life couple doing a comedy show together is usually a rapid sinking of the heart. It’s a scepticism born of too many evenings with coupled-up friends who collapse into spasms of laughter every time someone says “couscous”, and then pretend-apologise by exchanging a special glance and saying: “Sorry, it’s hard to explain, it’s just… we have a thing about couscous.” Yes, hilarious.
Frequently, what couples find funny together fails to translate outside that context, and can often feel exclusionary – which, after all, is the point of a private joke: this is our thing, you wouldn’t get it because you weren’t there. So the prospect of that in sitcom form doesn’t inspire confidence.
