An elderly man was out for a leisurely walk in the park one day, when he came upon a morbidly obese kid sitting on a park bench.
The kid was steadily shoveling candy in his mouth and washing it down with soda. There was a huge pile of candy wrappers on the ground around him.
The old man said “My God son! You can’t keep eating like that, how old are you kid?”
The kid swallowed his candy and looked up at the old man and said “I’m 12 years old!”
The old man said “Well if you keep eating and drinking that crap, you probably won’t make it to 20 years old before you have a heart attack!”
The kid said “Well, my grandfather lived to be 116 years old.”
The old man said “Well I bet he didn’t live that long by eating candy and drinking soda all day!”
The kid said “No, but he knew how to mind his own freaking business!”
