Orphan's Photo

Alright, listen up, you big dummy. You posted a joke, which means you need help understanding it. Here's the deal: an orphan is a kid with no parents, right? And a 'family photo' needs a family. So, when an orphan takes a picture, it's just a picture of themselves, get it? Like a 'selfie'. It's wordplay, you silly goose! It's funny because the two meanings of 'selfie' overlap - it's a photo one takes of themselves and its also what a orphan has to take because they are by themselves.
