A 90-year old man said to his doctor "i've never felt better. i have an 18 year old bride who is pregnant with my child, so what do you think of that?"
The doctor considered his question for a minutes and then said "i have an elderly friend who is a hunter and never missed a season. one day when he was going out in bit of hurry, he accidentally picked up his umbrella instead of his gun. when he got to the creek, he saw a rabbit sitting beside the stream. he raised his umbrella and went 'bang bang' and the rabbit fell dead. what do you think of that.?"

the 90-year old said "i'd say somebody else killed that rabbit."

the doctor replied "that's exactly my point.
