After marrying a young filly, a ninety-year-old geezer told his doctor that they were expecting a baby.

"Let me tell you a story," said the doctor. "An absent-minded fellow went hunting, but instead of a gun, he picked up an umbrella. Suddenly a bear charged him. Pointing his umbrella at the bear, he shot and killed it on the spot."

"Impossible!" the geezer exclaimed, "Somebody else must have shot that bear."
