Good Old Dad
A guy goes to the supermarket and notices an attractive woman waving at him.
She says hello, and he’s rather taken aback because he cant place where he knows her from.
So he says, “Do you know me?”
To which she rplies “I think you’re the father of one of my kids.”
Now his mind travels back to the only time he has ever been unfaithful to his wife and he says “ My god, are you the stripper from my friends bachelor party, that I made love to on the pool table with all my mates watching while you partner whipped my arse with a wet mackerel??”
She looks into his eyes and says calmly “No I’m your son’s teacher!”
