Orphan's Fate

Alright listen up, you dummy. You see, the joke plays on the saying "The apple doesn't fall far from the tree," which means kids are like their parents. Orphans don't HAVE parents, so the joke implies orphans die young because they don't have a family history to live long. But you probably think a family tree is just a place where you hang your relatives after they annoy you, don't you?
