Doctor: Why are you so happy?
Old Man: My 19 year old wife is pregnant! Can you believe it?!
Doctor: Wow, that great news! You know, I have a story to tell you.
Old Man: Go ahead
Doctor: I once had a friend. He would go hunting every weekend. One day he forgot to bring his gun. He brought his umbrella instead.
Old Man: Ok...
Doctor: He then saw a bear. Not knowing what to do, he opened the umbrella, and poof, the bear died.
Old Man: How's that possible? You can't kill a bear with an umbrella
Doctor: Exactly. Somebody else must've shot the bear.
