Bad Pain

A 70 year old man went to his doctor’s office complaining about a pain in his private parts. The doctor gave the man a jar and said, “We will start with a sperm test. Take this jar home and bring me back a sample tomorrow.” The next day the 70 year old man reappears at the doctor’s office and gives him the jar, which is as clean and empty as on the previous day.
The doctor asked what happened and the man explains: “Well, doc, it’s like this: First I tried with my right hand, but, nothing. Then I tried with my left hand, but still nothing. Then I asked my wife for help. She tried with her right hand, then her left, but nothing. She even tried with her mouth, teeth in, teeth out, and still nothing. We even called up the lady next door and she tried with both hands and her mouth too, but nothing.”
The doctor was shocked! “You asked your neighbor?” The old man replied, “Yep, but no matter what we tried we couldn’t get the darn jar open!”
