|A housewife is at home when she suddenly hears a knock on the door.
When she opens the door, a man asks her if she has a vagina.
The woman slams the door in disbelief of what a stranger has just asked her.
The same thing happens three consecutive days, so the woman decides to fill in her husband.
The husband tells the wife, "Tomorrow I am not going to work; when the man asks if you have a vagina, say “yes,” and I will be hiding behind the door."
The next day the very same man comes by and, when the woman opens the door, he asks if she has the vagina; the woman answers "Yes."
The man then related to the woman, "Good! Then please tell your husband to stop screwing my wife!"
