Two men are in a doctor's office. Each of them to get a
vasectomy. The nurse comes into the room and tells both men,
"Strip and put on these gowns."

A few minutes later she returns and reaches into one man's
gown and proceeds to fondle him, and ultimately begins to
masturbate him.

Shocked, he asks, "Why are you doing that?"
To which she replies, "We have to vacate the sperm from your
system to have a clean procedure."

The man, now understanding and also enjoying it, allows her
to Complete her task. After she is through, she proceeds to the
next man. She Starts to fondle the man as she had the previous man, but
then drops to her knees and proceeds to give him oral sex.  The first man,
seeing this quickly responds, "Hey! Why is it that I get masturbated,
but he gets a blowjob?"

The nurse simply replies, "That sir, is the difference
between the NHS and BUPA."
