Married at first sight...

[Greg Bobkin]

IIRC, wasn't it done on Radio, with Jeremy Kyle hosting it, and he ended up marrying the woman from it?

Then made an episode of his show out of it when it all when wrong?

Watch out for the sequel - "Car keys on the coffee table"

A documentary where married couples who are not happy with their spouse go to "parties" for a random shag fest with a stranger.

You see I would watch and sign up for this...
