An elderly man storms into his doctor’s office steaming mad.
“Doc, my new 22-year-old wife is expecting a baby. You performed my vasectomy 30 years ago, and I’m very upset right now.”
“Let me tell you a story,” the doctor calmly replies.
“A hunter once accidentally left the house with an umbrella instead of his rifle. Out of nowhere, a bear surprised him in the woods… so the hunter grabbed the umbrella, fired, and killed the bear.”
“Impossible, ” the old man says. “Someone else must have shot that bear.”
“You got it,” the doctor replies.
