There is this kid who walks into this store and buys three snickers bars. The kid walks over to a bench in the store, sits down and eats every candy bar, 1, 2, 3, gone. An old man from across the store sees the kid eat the candy bars.

The old man walks over to the kid and says, "You know kid, eating candy bars like that and eating all that sugar isn't all that good for you".

The kid replys "You know old man, my grand dad lived to be nintey-three years old".

And the old man says, "From what watching what he eats and exercising?".

The kid replys, "No, from minding his own fucking business".
