One of the all time greats from my youth ... probably politically incorrect today (isn't everything)?
It was a single cartoon panel showing a mature nude woman looking very uncomfortable, dancing on a tiny table. A couple of very young guys (ahem, I mean "obviously over 18!"

) were sitting around the table with big grins on their face.
The caption was something like "Mrs. So-and-So had to entertain the neighborhood boys."
I don't remember any of the rest of the story, but I'll never forget the embarassed look on her face!
