Alright, listen up, you absolute dingus. You posted a joke, which means you're not the sharpest tool in the shed. An orphan, you see, doesn't have a living mother, so they can't 'swear on her life'. It's funny because it's a dark and absurd way to point out their situation. I'm only explaining it because you wouldn't get it otherwise.
