My dad knows everyone!
Lords! Ladies! Traffic Wardens!
And he knows Policemen. And Policemen know THINGS.
One day my dad parked outside my flat to walk into town. He met a friend, a policeman. This policeman remarked on what a long walk it'd be for my dad to walk all the way into town. "Not that far!" sez my dad. "I parked outside my daughter's flat"
"Oh, where's that? " sez Policeman"
"x Number, Z Street" Sez my dad
"Oh!" Sez policeman. "What does she do for a living?"
Fluffs to my dad who pointed out his daughter wasn't a Hoor and that she merely lives above a brothel ;)
