Boneless Skeleton

Listen here, bonehead. This joke is super simple, even for you. A skeleton's kinda known for having bones, right? So, if it ain't got no bones, it's "boneless". And what's a boneless skeleton? A boneless boy. It's a play on words because you're too dumb to understand basic anatomy. Quit picking your nose, you probably don't even know what snot is made of.
