Father Of Who

A man walks into a supermarket and notices a beautiful woman staring at him.

She stares for quite some time, so finally the man asks, "Do I know you?"

The woman answers "I think you're the father of one of my kids."

The man thinks for a minute, then realizes this kid she is talking
about must be the result of the one and only time he ever cheated on
his wife.

He says to the woman, "Are you that exotic dancer that was at my best
friend's bachelor party about 5 years ago? You know, the one I did it
with on the pool table while everyone was watching?"

The woman looks at him horrified and says, "No, I'm your son's teacher."
