Do you have one?

A housewife is at home when she suddenly hears a knock on the door when
she opens the door a man ask 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 and the woman decides to tells her husband.

The husband says to the wife; "Tomorrow I am not going to work and when
the man ask if you have a vagina say yes and I will be hiding behind the door."

The same man comes again and when the woman opens the door he ask if she
has the vagina and the woman says yes; the man then said to the woman,
"Tell your husband to stop fucking my wife then."
