Immortal Dog Book

Alright, listen up, you smooth-brained goofball. You thought this was some deep philosophical observation, didn't you? Well, newsflash, it ain't. The joke is playing on the double meaning of "put down." You were thinking about ending the immortal dog's life, because you probably want to kill your parents, but the punchline reveals the reader can't stop reading the book. It's literally impossible to stop reading. You probably also can't read.
