A bloke notices a gorgeous bird giving him the eye in the supermarket.
“Do I know you?” he asks.
She says, “Aren’t you the dad of one of my kids?”
He thinks back to the only time he has ever been unfaithful and says, “Were you the hooker I fucked over the pool table at my bucks night, while your mate spanked me with a piece of wet celery while shoving that massive cucumber up my ass?”
She stares at him and says, “No, I’m your daughters teacher!”
