"I think I have a problem, Doc," says the patient, "One of my balls has turned blue."
The doctor examines the man briefly and concludes the patient will die if he doesn't have his testicle removed.
"Are you crazy?" bursts the patient, "How could I let you do such a thing to me?"
"You want to die?" asks the doctor rhetorically, and the patient has to agree to have his testicle removed.
Two weeks after the operation, he comes back. "Doc, I don't know how to say this, but the other ball has turned blue, too."
Again, the doctor tells him if he wants to live, his other testicle must be cut off, too and, again, the man is very reluctant to the idea.
"Hey, you want to die?" asks the doc, and the patient has to agree with the operation.
But, about two weeks after he is testicleless, he returns to the doctor.
"I think something is very wrong with me. My penis is now completely blue."
After briefly examining the patient, the doc gives him the bad news: if he wants to live, his penis has to go. Of course, he does not want to hear about it.
"You want to die?" asks the doctor.
"But... how do I pee?"
"We'll install an plastic pipe, and there will be no problem."
So, he has his penis removed, and, a while after the operation, the unfortunate man enters, again, the doctor's office. He is very angry.
"Doctor, the plastic pipe turned blue!"
"What?"
"Can you tell me what the hell is happening!?"
So, the doctor examines the patient more carefully and says, "Hmmm, I don't know, could it be the dye from your blue jeans?

Too funny 
That's great.
