Stop me if you've heard this one.
A man goes to his doctor for a checkup. After examining him thoroughly, the doctor says, "John, you're in surprisingly good health. You're fit, you're strong, and all your blood work came back great. You've got the body of a 35 year old man. Just how old are you anyway?"
"I'm 76," John replies.
"That's amazing!" exclaims the doctor. "What do you do to stay so fit?"
"Well," John explains, "I get up ever day before dawn, I head out up the mountain, and I go turkey huntin'."
The doctor rubs his chin thoughtfully and says, "That certainly is good exercise, but there must be more to it than that. I'd bet you've got really good genes. Tell me, how old was your father when he died?"
"Who said he was dead?" retorted John.
"You're dad's still alive? How old is he?" the doctor asks.
"Your dad's 97? Wow! That's great. What is his secret?"
"Well, every morning he gets up before dawn, we walk up the mountain together, and we go turkey huntin'."
The doctor is absolutely amazed. "That's incredible. Your dad is 97 years old and he goes turkey hunting with you? That's -- that's just incredible. You must have incredible genes in your family. Tell me, how old was your grandfather when he died?"
"Who said he was dead?" replies John dispassionately.
"What!? Your grandfather is still alive?"
"How old is he?"
"He's 118 years old."
"What?!" exclaims the startled doctor. "Come on! I'll bet next you're going to tell me he went turkey hunting with you this morning."
"Nope. He couldn't. He was getting married this morning."
The doctor is bewildered and says, "Getting married? Why in the world would a 118 year old man want to get married?"
"Who said he wanted to?"
