A 90 year old geezer married a very young filly and was telling his doctor that they were expecting a baby.

"Let me tell you a story," the doctor said. "There was an absent-minded fellow who went hunting one day, but instead of picking up a gun, he picked up an umbrella. Suddenly, while he was out in the woods, a bear charged him. He pointed his umbrella at the bear, shot and killed it on the spot.

"Not possible!" the old geezer exclaimed. "Someone else must have shot that bear."

"Exactly!" the doctor replied.
