Shooting blanks

80 year old man: My 28 year old wife is pregnant, 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 woods, sees a bear, lifts the umbrella, pulls the handle and BANG... The bear drops dead!

Old man: Thats impossible; someone else must have shot the bear.

Doctor: MY POINT EXACTLY!
