So this guy is having terrible headaches...

So he goes to the doctor to determine what is wrong. The doctor states that the patient has a rare condition where his testicles are pressing against the base of his spine causing the excruciating headaches.
"How do I fix it?" asks the patient.
"The only solution is castration" says the doctor.
The guy immediately refuses, but after another day he can't stand it and goes back and opts for the procedure.
The headaches disappear.
The guy thinks with this new start on life headache free, he should get a new suit
So he heads to the tailor.
"How can I help you?" Asks the tailor.
"I'd like to buy a new suit" says the man.
"Sounds great, what would you like?" Asks the tailor.
"I'd like a new hat" says the guy.
The tailor looks at him and says, "you look like a 14."
"That's amazing! How did you know that?" Says the guy.
"I've been a tailor for 25 years, that's my job. What else would you like?"
"I'd like a new shirt" says the guy.
"Let me see" as he looks the guy over, "you look like a 18 long."
"Thats incredible! You didn't even use a tape measure" Says the guy.
"As I said, I've been a tailor 25 years... what else?"
"I'd like a new pair of pants" says the guy.
"34/32" says the tailor.
"I don't even.." says the guy.
"25 years" says the tailor, "what else?"
"I'd like some new underwear" says the guy.
"You're a large" says the tailor.
Immediatley the guy laughs and says, "HA! You're wrong. I'm medium. I've been a medium for years."
"You couldnt be a medium" states the tailor. "If you were, your testicles would press against the base of your spine and cause terrible headaches."
