I from the US, just learned about these today, and had a chuckle.
an essex girl was driving down the A13 when her car phone rang. it was her boyfriend, urgently warning her “treacle, i just heard on the news that theres a car going the wrong way on the A13. please be careful!” “its not just one car!” said the essex girl “theres hundreds of them!”
They definitely are!
I had a thought about finding similarly themed jokes about men, but haven’t had any luck yet. It’s true that a good number of blond jokes could be gender agnostic so long as they are just about intelligence.
