Did you ever hear the story about the broken pencil?
That's okay. There is really no point to it.
Listen up, nimrod. This joke is all about wordplay, see? "Point" usually means the pointy end of a pencil. But in this joke, it also means that there's no "point" to the story, like it's useless. Get it now? You're probably the kinda guy who still uses a No. 2 pencil for everything, huh?
