Whats Your Opinion

An 80yr old man says to his doctor: My 28yr old wife is pregnant,
what's your opinion doctor
Doctor: let me tell you a story, a hunter in a hurry grabs an umbrella instead of the gun. He moves into the jungle, sees a lion, lifts the umbrella, pulls the handle and Bang.......... The Lion drops dead!
Old man: That's impossible, someone else must have shot the lion.
Doctor: MY POINT EXACTLY.
