A 75-year old man went to his doctors office to get a sperm
count. The doctor gave the man a jar and said, Take this jar home
and bring me back a sample tomorrow. The next day, the 75-year old
man reappears at the doctors office and gives him the jar, which
is as clean and empty as on the previous day.
The doctor asks what happened, and the man explains
..
Well, doc, its like this. First I tried with my right hand, but
nothing. Then I tried with my left hand, but nothing.
Then I asked my wife for help. She tried with her right hand, but
nothing. Then her left, but nothing. She even tried with her mouth,
first without her false teeth, then without her false teeth, and
still nothing.
Hell, we even called up the lady next door, she tried with both
hands and her mouth too, but nothing.
The doctor was shocked. You asked your NEIGHBOUR???!!!
The old man replied, Yep, but no matter what we do or how hard we
tried, we couldnt get the damn jar to open!!!
What were you thinking my friends?
