Orphan's Oath

Listen up, chucklehead. This joke is about an orphan, see? Orphans ain't got no parents, and in this case, no friends either. So, when the preacher-man asks them to swear on something important, the kid realizes they're all alone in the world. It's funny 'cause it's sad, and you're probably too dense to realize how tragic that is. It's called dark humor. I bet you thought the opposite of up was down, ya jabroni.
