Two men are sitting in a pub talking, one mentions that its his wifes birthday soon and he doesnt know what to get her.

The second man says that he bought his wife a blue Porsche and a red Porsche for her birthday because if she didnt like the blue one, she could have the red one, and vice versa.

The next week, the second man asks the other what he finally bought his wife. He replies, a necklace and a vibrator.

Why? asks the second man.

To which the other man replies, Because if she doesnt like the necklace, she can go fuck herself.
