A rich man and a poor man are talking when the poor man says to the rich man, "My wife's birthday is this week and I don't know what to get her. What did you get your wife for her birthday?"
The rich man says, "I got her a diamond necklace and a Mercedes"
When the poor man asks why he bought her both gifts, the rich man replies "If she doesn't like the necklace, she can take it back to the jeweler in her Mercedes and she'll still be happy."
A few weeks later the two men cross paths and the rich man asks the poor man what he ended up getting his wife for her birthday. The poor man responds, "I got her a dildo and some sandals, so if she doesn't like the sandals she can go fuck herself."
