An 86 year old went to his doctor for his quarterly check-up.  The  
doctor asked him how he was feeling, and the 86-year-old said: "Things  
are great, and I've never felt better.  I now have a 20 year-old bride  
who is pregnant with my child.  So what do you think about that, Doc?"

The doctor considered his question for a minute and then began to tell  
a story. "I have an older friend, much like you, who is an avid hunter  
and never misses a season.  One day he was setting off to go hunting.  
In a bit of a hurry, he accidentally picked up his walking cane  
instead of his gun.  As he neared a lake, he came across a very large  
male beaver sitting at the water's edge."

"He realized he'd left his gun at home and so he couldn't shoot the  
magnificent creature.  Out of habit he raised his cane, aimed it at  
the animal as if it were his favorite hunting rifle and went 'bang,  
bang'.  Miraculously, two shots rang out and the beaver fell over  
dead."  "Now, what do you think of that?" asked the doctor.  The  
86-year-old said , "Logic would strongly suggest that somebody else  
pumped a couple of rounds into that beaver."

The doctor replied, "My point exactly."
