Having A Wank

A cop was walking his beat through a back alley when he caught Little Johny having a wank behind some bins.

"What do you think you're doing?" the cop asked.

"What does it look like I'm doing? I'm having a wank," Little Johny replied.

"You'd best be careful, boy," the cop warned. "When we catch a young fellow doing that, we cut off his pecker and make a police baton out of it."

"I bet I know what you do when you catch a girl doing her thing," said Little Johny.

"And what's that?" asked the cop.

"You cut out her pussy, then dress it in a blue uniform, and call it a cop!"
