Two men are in the doctor’s office waiting to get vasectomies. A nurse comes in and asks the men to strip and put on their medical gowns while they wait for the doctor.

Minutes later she comes back, reaches under one man’s gown and begins to masturbate him.

Shocked, he says, “My God, what are you doing?”

To which she replies, “We have to vacate the sperm from your system in order to have a clean procedure.”

Not wanting to cause a problem, the man relaxes and enjoys it as she completes her task.

The second man watches all of this and by the time the nurse turns to him, he is quite ready.

To his surprise, she drops to her knees, opens her lips and begins to give him a blow job.

The first¬† man says, “Hey, what is this? Why is it that I get a hand job and he gets a blow job?”

The nurse says, “That, sir, is the difference between an HMO and Blue Cross.”
