Orphan's Selfie

Hey, listen up, buttercup. This joke is funny because orphans don't have families, right? So, a "family portrait" is a picture of… well, a family. But an orphan taking a selfie and calling it that? It's ironic, see? Like calling your empty fridge a buffet. You wouldn't get it, because you're probably too busy trying to figure out which end of the fork to use, genius.
