Oops
Guy goes into a supermarket. A lady approaches and says, "Excuse me, are you John Lambert?"
Guy says, "Yes, I am. Why do you ask?"
She says, "I think you're the father of one of my kids."
He looks embarrassed and says, "I'm sorry, are you the stripper from Barry Brown's stag party in 2015?"
She says, "No, I'm your son's primary school teacher."
