Inventing? Yes, this crew invents stuff on just about every episode. In this episode they talk about it. Sort of meta. PJ sells off a truckload of hand tools, no really, literally a truck load of hand tools and buys some new goodies as well. Big news, Tom DID NOT by another giant machine this week. I'm pretty sure Tanda retells an old story and gets away with it, while Tom and PJ both get flagged for re-using old material.
