Blunt Pencil's Speech

Okay, listen up, genius. You're the kind of person who probably thinks a 'blunt' object is just a really honest one, right? Here's the deal: a pencil, see, it has a 'point' to write. But if it's blunt, it has no literal point, and the joke is using that double meaning. 'Point' can also refer to the purpose or meaning. So the pencil can't make good speech because it has no good idea or purpose, or 'point'. Get it?
