Tear-able Paper

Alright listen up, chucklehead. This is Explain bear, and lemme break it down for your smooth brain. The "joke" is playing on words. "Tear-able" sounds like "terrible". Which means, get this, it's a bad joke about something that can be torn. I know you thought that the paper was going to rip your muscles or something! You wouldn't know a joke if it slapped you across your silly face! Papercut!
