Headache.

i have one right now.

Reminds me of this joke i heard before.

A guy has a constant headache, its so bad that its affecting everything in his life, his work, his marriage. So he goes to see a doctor.

Guy with a heahache: Doctor, i have this constant headache. Is there anything i can do about it?

After extensive tests.

Doctor: I'm afraid that your testicles have to be removed to cure your headache, they are pressing against a nerve which causes your head to have a dull throbbing.

Guy is desperate: Alright, I'll do anything to stop the headaches.

A few months after the operartion, the guy's wife left him, but at least he's no longer having headaches.

One day, he went to the tailor to get some pants made.

Tailor: Alright, you're a size 35.
Guy: I'm sorry but i usually wear size 33.
Tailor: I see, you could wear a size 33, but it'll pinch your balls and give you a blinding headache.

Heh.
