My father-in-law often talks about Garreth The Gas...Most common in Wales thus giving rise to a very old joke, in shortened form:
As in most Welsh villages, everyone had the same surname, so were identified by their profession. Hence, there was Evans the post, Teacher Evans, Painter Evans, Evans the milk, and his brother, the crossing keeper Level Evans.
Level Evans got involved in a bar room brawl one night, and killed his opponent (probably called Evans). He was hauled off, tried, convicted and sentenced to hang.
He was eventually granted a reprieve and when word reached the village a crowd formed outside the home of his brother Evans the Milk, who was in the bath. They hammered on the door, and Evans the Milk leapt from the bath, and rushed to the door without bothering to dress.
As the door opened the mob shouted in unison:
'They're not hanging level Evans'.
