a man is out shopping one day...

...when he sees a blonde is looking at him. She waves over and he says to her, "I'm sorry but do I know you?"

She says, "I think you might be the dad of one of my children!".

A little shocked, the man casts his mind back to the one and only time he had been unfaithful.

He says, "are you the stripper from my stag do that I shagged over the snooker table while your mate whipped me and stuck a cucumber up my &rse?".


She replies, "No, I'm your sons English Teacher".
