Doc: Well Mr. Smith, you're fit as a fiddle for an 80 year old. How do you do it?
Smith: Squirrel hunting. Keeps a man young and healthy. I went hunting before I came here this morning.
Doc: I think heredity has something to do with it. How old was your Dad when he died?
Smith: Who said anything about my Dad being dead? He went squirrel hunting with me today.
Doc: What?? He must be a hundred years old!
Smith: 102. Loves to hunt.
Doc: Well how old was his Dad when he passed away?
Smith: Who said anything about my grandpappy being dead?
Doc: That's impossible. He'd have to be close to 120.
Smith: 121 to be exact.
Doc: Don't tell me he went squirrel hunting with you and your Dad this morning.
Smith: No, he didn't. He was getting himself married.
Doc: You're kidding! Why would a 121 year old man want to get married?
Smith: Who said anything about him wanting to get married?
