There's the man who has this terrible headache which starts at the front, spreads to the sides and then to the top of the head. He goes to a doctor and explains his terrible headache, starting at the front, spreading to the sides and then to the top of the head. The doctor does every possible check like computer tomography, blood pressure and so on. He can't find a reason for the headache.

So the man tries a second, a third, a fourth doctor, none of them can help him get rid of his terrible headache, starting at the front, spreading to the sides and then to the top of the head. The fifth doctor also checks the man, and after a while he says: "There is only one way to cure a terrible headache, starting at the front, spreading to the sides and then to the top of the head. I'm sorry but I can only cure it if I remove your balls!" Of course, the man protests.

But the headache continues, and no drug is able to help with the pain. So after a few days he goes back to the fifth doctor and has his balls removed. After the operation the headache vanished.

After the man is released from hospital, he wants to buy himself a new suit as a sort of recompensation for his lost balls. So he goes to a taylor. While the taylor is measuring the man, he asks whether the man wears his dick to the left or to the right. The man answers he doesn't care as it does not make any difference.

The taylor replies: "Oh, but it makes a big difference! If you wear it on the wrong side, you might get this terrible headache, starting at the front, spreading to the sides and then to the top of the head!!!"
