Papyrus breaks a cell bone

Alright, listen up, buttercup. So, Papyrus, right? He's playing around and ends up breaking a "cell-bone" of the human. Now, this ain't no ordinary bone, it's a pun on "cell phone." Get it? Cause you ain't too bright, I had to spell it out. By the way, people who can't figure out simple wordplay probably still use flip phones.
