Can Elis James find a mutual connection to every Welsh person?
The old expression that everyone in Wales knows each other is being put to the test in a live radio segment.
Every week BBC presenter and comedian Elis James, from Carmarthenshire, gets 60 seconds to find a mutual connection with a random Welsh caller on his Radio 5 Live show.
The hurried and tense one-minute exchanges have had hundreds of thousands of views across TikTok, YouTube and Instagram, with listeners from outside Wales often amused - if slightly baffled.
As the Cymru Connection theme music kicks in, James is often seen putting his head in his hands.
"I find it immensely stressful," said James, who has a more than 50% success rate from 30 callers tested so far.
Elis James & John Robins airs at 13:00 GMT on Fridays on BBC Radio 5 Live and the podcast is available on BBC Sounds.
