Couple go to the clinic and are told they need to undergo some simple preliminary examinations.
The nurse leads the guy to a cubicle, gives him a bottle and says, "The Doctors need a sperm sample just to see how things are down there. Ther''s a lock inside the door and just come out when you''re finished."
Quarter of an hour later the nurse knocks on the door. "Are you all right in there?"
"Yes, thanks...I''m OK..just need a bit more time."
The nurse goes away and gets some Girlie Mags and chaps on the door.
"Hello..if you open the door a bit I can hand in some things that may help."
So the guy unlocks the door and opens it a little bit and she passes the mags through.
Quarter of an hour later she comes back and chaps on the door. "How are we doing? Any success yet?"
"Not yet" came the reply, "I''ll need a little bit more time."
Quarter of an hour more passes and the nurse chaps on the door again..
"Look, I''m awfully sorry, but thats nearly an hour now and we have a lot of patients to see this afternoon and need this cubicle. Maybe you could rearrange another appointment at reception, but we really do need this room now."
So the guy unbolts the door and comes staggering out, all red faced and sweating and hands the bottle with shaking hands to the nurse.
She looks at it and says "Oh well done! So you DID manage a sample after all!"
He looks at her in puzzlement and says..
"Oh! I thought I had to FILL the bottle!"
