A husband and wife are sitting at the kitchen table making their Chrstmas List. They finish and the husband goes to work and the wife decides to go shopping.

The next day the grocery boy comes to the door and the wife says "Here is you Christmas present, Merry Christmas." Then the milk man comes to the door and she says the same thing.

Then the mail man comes to the door and she says "Why don't you come in for a little while"

So the milk man goes in and the wife goes upstairs. The milk man follows her to the bedroom. She strips off her clothes and lays spread eagle on the bed and says "Well don't you want to fuck me?" The mail man looks around, takes off his clothes and they start fucking.

Well, the husband comes into the room and asks "What the hell are you doing?" and the wife replies "What you told me to do, Fuck the Mail Man."
