Interesting. In the UK (at least when I was growing up, I haven’t lived there for some time) we called doing up shit cars as Barry-ing them. I know in other parts of the country they used the name Ned or Kev to refer to the people that drove those cars.
Can I suggest “What dish is made when a hen stares at lettuce?”
Something about having part of the punchline in the set-up always irks me.
