Gay bloke goes into a bar in Liverpool, sits down at the bar and orders a pint. He turns and starts looking at the bloke on the next bar stool and finds him irresistible. Knowing he might get knocked back, he sidles over and whispers "would you like a blow job?"

The other bloke jumps to his feet and smacks the gay in the mouth, drops him to the floor and proceeds to kick and punch him until he's unconscious and bleeding.
He returns to his stool, where the barman asks, "what happened Kev? What did he say to yer?"
"I'm not, sure," says the geezer, "something about a job."
