Two men were in the doctor's office. Each of them is there to get a vasectomy.
Nurse comes into the room and tells both men to, "Strip and put on these gowns before going in to see the doctor to have your procedure done."
A few minutes later, she returns and reaches into one man's gown and proceeds to fondle his pecker, and ultimately begins to masturbate him.
Shocked as he is, he asks, "Why are you doing that?"
She replies, "We have to vacate the sperm from your system to have a clean procedure."
The man, not wanting to cause a problem (and enjoying it) allows her to complete her task.
After she is through, she proceeds to the next man. She starts to fondle him as she had the first man, but then drops to her knees and starts to suck him off.
The first man, seeing this, quickly asks, "Hey! Why is it that I get jerked off and he gets a blow job?"
The nurse simply replies, "That's the difference between Medicare and Private Health Insurance coverage."
