A man walks into a supermarket and notices a beautiful woman staring at him.
After a while, he finally asks, “Do I know you?”
She replies, “I think you’re the father of one of my kids.”
The man’s heart stops. He thinks back to the one time he ever cheated on his wife.
He nervously asks, “Wait… are you the stripper from my best friend’s bachelor party? The one I, uh… met on the pool table while your friend spanked me with a whip?”
The woman looks absolutely horrified.
“No,” she says. “I’m your son’s teacher.”
