An old couple goes to the doctor. The man says, "We want to know if we're makin' love properly. Will you watch us?"
The doctor says, "Go ahead." So they go to it.
The doctor says, "Looks good to me... That'll be forty dollars."
They go back six weeks in a row and do the same thing each time.
On the seventh week the doctor says, "Why do you keep coming back? I told you, you're making love perfectly."
The old guy says, "Well, she can't come to my house, and I can't go to her's...a motel is fifty bucks...you only charge us forty and we get back thirty-five back from Medicare."
A woman is at home when she hears a knock at the front door. When she opens it there's a man standing there who shouts at her: "Hey lady, do you have a vagina?" Scared, she slams the door shut hoping he'll go away.
The next morning she hears a knock at the door again. It's the same guy and he asks the same question. "Do you have a vagina?" And again she slams the door only this time she calls her husband. The husband tells her he'll take off from work the next day and find out exactly what this guy is up to.
So the next morning, with the husband hiding behind the door, here comes that knock again. The husband signals to his wife she should answer yes this time. When she opens the door and the guy asks, "Do you have a vagina?" the wife says, "Yes I do."
"Perfect" the man replies, "Tell your husband to leave my wife's alone and start using yours!"
