I'm stealing this one from The Sopranos:
A rich guy and a poor guy are good friends who meet every month for lunch.
One month the rich guy says, "It's the wife's birthday next week"
The poor guy asks what he is getting her.
"I'm buying her a diamond necklace and a brand new Mercedes Benz" says the rich guy.
"Why two gifts?" asks the poor guy.
"Well, I love my wife so much that I want her to have the best and never be disappointed. By buying her the car, she has the ability to drive it to the jewely store and exchange the necklace if she doesn't like it." answers the rich guy.
The poor guy is impressed and they end their monthly lunch.
The next month comes along and the two men meet up again.
"It's my wife's birthday next week." states the poor guy
"Oh yea, what are you getting her?" the rich guy asks.
"I bought her a pair of slippers and a dildo" says the poor guy.
"Why two gifts?" his friend asks.
He replies "Well, if she doesn't like the slippers she can go diddly herself"
