After marrying a sweet young woman, a 90-year-old gent tells his doctor that they are expecting a baby.
"Let me tell you a story," says 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."
"But that's impossible!" the old man exclaims. "Somebody else must have shot that bear!"
"Exactly my point," replies the doctor.
