One day, at the doctor's office...

An old man, well into his eighties, goes to a doctor for a regular checkup.

The doctor examines him, makes several tests, looks at him and he can't believe what he sees. He says, "Sir, this can't be true! Physically, you’re well into your senior years, but you're healthy as a teenager. No hypertension, no elevated sugar levels, your ECG is perfect... How is that possible?"

"Well," the old man replies, "probably because I'm physically active. You see, I walk every day, I go fishing regularly..."

"No," the doctor interrupts him, "that couldn't possibly explain this phenomenon. This must be genetic. Tell me, how old was your father when he died?"

"My father’s not dead!” the old man replies. “He's alive and well, just like me. We even go fishing together."

The doctor is blown away by this. With a shaky voice, he asks, "How old is he?"

"Almost a hundred. He married young."

"Wow! That’s phenomenal! Now, how about your grandfather? Can you remember how old was he when he died?"

"He's not dead either! He's almost 120."

Now the doctor is skeptical.

"I guess he too goes fishing with you and your father?"

"Oh, no, this week he'll be at home, he's preparing for his wedding"

"He's 120 years old and he wants to get married?"

“Who said he WANTS to?

“Wait…” the doctor says, “You’re telling me he got some girl PREGNANT, and now he’s MARRYING her???”

"Well, he doesn't really want to, but his parents are nagging him..."
