Joe is on his last day at work as a mailman.
He receives many thank-you cards and monetary gifts along his route.
When he gets to the very last house, he is greeted by a gorgeous housewife, who invites him in for lunch. Joe happily accepts. After lunch, the woman invites him up to the bedroom for some 'desert.' Joe happily accepts again. When they are done, the woman gives him a dollar.
Joe asks what the dollar is all about.
The woman replies: "It was my husband's suggestion. When I told him that it was your last day at work, he told me screw him -- give him a dollar.' The lunch was my idea."
