This might be an old one, but I just heard it, so I thought I'd pass it on.

A guy is at the supermarket when he sees a pretty blond that looks familiar to him, but he can't place her. Surprisingly, she wheels her cart over and says, "Hello."  

"Do I know you?" he asks.

"Yes," she says, "You are the father of one of my kids."

He thinks hard for a minute, and then says, "Wait. Are you that hooker that I spent a weekend with a couple of years ago down in Myrtle Beach, and we had the most amazing anal and bondage sessions?"

"No," she replies. "I'm your son's math teacher."
