Skele-Ton of Work

Listen up, bonehead! You see, it's a play on word. A "ton" is a unit of weight, and they replace it with "Skele-ton" because skeleton is the main figure of the joke. It's like, they're using the word 'skeleton' in a punny way with 'ton' to make it sound like a lot of work. Get it now, or do I need to spell it out with femur bones?
