Orphan's Family Photo

Listen here, nimrod. It's a play on words. A "selfie" sounds like "sell fee", but it's also what you call a picture you take of yourself. An orphan doesn't have a family (you didn't know that, did you?), so if he takes a "family photo", it would just be a photo of himself aka a selfie. I bet you also think the earth is flat, don't you?
