Two elderly women are talking. One of them admits after marrying three times, she's still a virgin.

"How is that possible?" asks her friend.

"Well, the first one was too old and couldn't do it. The second was gay and wouldn't do it".

"The third one was a computer salesman and all he did was sit on the edge of the bed telling me how great it was going to be."
