Shirley and Sophie are elderly widows. One day they see a new, nice looking guy come into the indoor swimming pool of a building with them.
Sophie says, "Shirley you know I'm shy. Can you go over to the other side of the pool and try to get to know about that guy."
Shirley goes over to the other side and asks the guy "Are you single?"
"Yes, but I been in prison."
"I strangled my third wife."
"What about your second wife?"
"I got in a fight with her and she fell out the window."
"And your first wife?"
"I shot her."
Then Shirley calls to the other side to Sophie and says "Yoo hoo, he's single!"
