Warning: May be NSFW (the older gentleman drops the f-bomb but at his age I think he's earned it).
This guy's son asks him how old he thinks he is and he says he's 79 years old. The only issue is he was born in 1919; which means he'll be 100 years old next year!
Seeing this older gentleman's response when he finds out how old he actually is, is perfect and classic!
I certainly hope I'm just like this guy when I'm almost 100 years old.
