There was this guy that went to the doctor to get his sperm counted.
The lady behind the desk handed him a jar and said, "Bring it back
tomorrow, full." He says, "Okay, I’ll be back tomorrow then."
Well he goes home and comes back the next day, and he hands the woman
the jar.
She says, "Nothing’s in it." The man responds, "Well, I went
home and I tried with my right hand and I tried with my left hand and
nothing happened. I called my wife into the room, and she tried with her
right hand and she tried with her left hand. Nothing still happened.
Well, we called our neighbor and she came over, and she tried with her
right hand and she tried with her left hand, and still nothing happened.
And the woman behind the counter looked stunned and asked, "You asked
your neighbor over to help you!?" And he says, "Yeah, we couldn’t get
the jar open."
