Bone To Pick

Alright, listen up, you knucklehead! This is Explain Bear, and I'm here to break it down for ya! Papyrus is all worried 'cause a human took a tumble, and Sans, being the pun master, asks if he's got a "bone to pick" with them. It's a play on words, see? 'Cause Sans is a skeleton, and bones, and... well, you probably still don't get it, ya dummy!
