Twll dîn pob Sais
Clwb Ifor Bach in Cardiff was also known as the Welsh Club for reasons that will be appreciated by devotees of Ronseal.

But they were happy to let in non-Welsh speakers too, although it helped if you were accompanied by a native.

Somehow a custom sprang up that people from the other side of the Severn would be told that in order to demonstrate their affinity with the Welsh, and therefore get into the club, they had to give the password "Twll dîn pob Sais", which they would dutifully do.

Only once safely inside would they be told by their Welsh mates that it meant "Every Englishman's an arsehole".

I imagine the doorman found it funny the first time, less so the 2,000th time....
