This 82-year-old man married a 22-year-old woman and they decided that they wanted to have kids. So after trying for a while with no success, he went to see the urologist, pretty discouraged. The urologist said not to get discouraged and that they could run some tests.

“Take this specimen jar into the bathroom and leave me a specimen to test,” the doctor said.

The old man closed the door, and about an hour and a half later, still had not come out. The doctor came by and asked, “Are you alright?”

“No” the old man said. “This just isn’t going to work.” he dejectedly explained. “There’s no hope for me, I’ve worn out my left hand, I’ve worn out my right hand, I’ve run cold water over it, and I’ve run hot water over it. I’ve even thumped it on the edge of the sink.

But no way can I get the top off this specimen jar!”
