He Kept Showing Up At Her Door With This Offensive Question. The Reason? Oh Lord

A woman is at home when she hears someone knocking at her door. She goes to the door, opens it and sees a man standing there. 

He asks the lady, "Do you have a vagina?" 

She slams the door in disgust. 

The next morning she hears a knock at the door. It's the same man and he asks the same question to the woman, "Do you have a vagina?" She slams the door again. 

Later that night, when her husband gets home, she tells him what has happened for the last two days. The husband tells his wife in a loving and concerned voice, "Honey, I am taking a day off tomorrow so as to be home, just in case this guy shows up again." 

The next morning, they hear a knock at the door and both head for the door. The husband whispers to the wife, "I'm going to hide behind the door and listen, and if it is the same guy I want you to answer yes to the question. I want to see where he's going with this." She nods yes to her husband and opens the door. 

Sure enough the same fellow is standing there, he asks, "Do you have a vagina?"

"Yes I do," responds the lady. 

The man replies, "Good, then would you mind telling your husband to leave my wife's alone and start using yours!"
