How to Cure a Headache

A guy has been suffering from severe headaches for years with no relief. After
trying all the usual cures he's referred to a headache specialist by his family
doctor. The doctor asks him what his symptoms are and he replies.
"I get these blinding headaches; kind of like a knife across my scalp and...."
He is interrupted by the doctor, "And a heavy throbbing right behind the left
ear".
"Yes! Exactly! How did you know?"
"Well I am the world's greatest headache specialist, you know. But I myself
suffered from that same type of headache for many years. It is caused by a
tension in the scalp muscles. This is how I cured it: Every day I would give my
wife oral sex. When she came she would squeeze her legs together with all her
strength and the pressure would relieve the tension in my head. Try that every
day for two weeks and come back and let me know how it goes".
Two weeks go by and the man is back, "Well, how do you
feel?"
"Doc, I'm a new man! I feel great! I haven't had a headache since I started
this treatment! I can't thank you enough.And, by the way you have a lovely
home."
