A 90 years old man goes to a doctor.
He said: “Doctor, my 28 years old wife is pregnant, what’s your opinion?”
Doctor replies: “Let me tell you a story. A hunter in a hurry grabs an umbrella instead of his hunting rifle.
He moves into the jungle, sees a lion, lifts the umbrella pulls the handle and….BANG!!! the lion drops dead!”
Old man exclaims: “That’s impossible! Someone else must have shot the lion.”
Doctor: “Exactly my opinion.”
