Grocery Store Mishap
A guy is in a grocery store when a pretty woman smiles at him and says hello. He's taken aback and can't place her.
"Do I know you?" he asks.
"I think you're the father of one of my kids," she says.
He racks his brain to think of how that could be. Then he remembers the only time he has ever been unfaithful to his wife.
'Wow," he says. "Are you the stripper from my bachelor party, who tied me down on the pool table, and did it with me, with my buddies cheering, while your friend sprayed whipped cream on my butt? Boy, that was insane."
"No," she says. "I think I'm your son's math teacher."
