The doctor slipped and cut off one of the man

While doing a vasectomy, the doctor slipped and cut off one of the man’s balls.

To avoid a huge malpractice suit, he decided to replace the ball with on onion.

Several weeks later the patient returned for a checkup.

“How’s your make love life?” the doctor asked.

“Pretty good,” the man said, to the doctor’s relief.

But then he added, “I’ve had some strange side effects though.”

“What’s that?” the doctor asks anxiously

“Well, every time I piss, my eyes water.

When my wife gives me a blow job, she gets heartburn, and every time I pass a hamburger stand I get a hard-on!”
