An old man, aged 90, tells the doctor:
“I never felt as good as I feel now. I have an 18 years old wife who is pregnant now. What do you say about this ?”
The doctor thinks a little then says:
“I have a friend who is an old man too and he likes hunting. He is not missing from any hunting season. One day he rushed and took the umbrella instead of the rifle. When he came into the woods he saw a hare standing near a river. He raised the umbrella, made a bang and the hare fell dead. What do you say about this ?”
The old man replies: “I think someone else shot his hare”.
Doctor: “Exactly !”.
