It's so hard to pick a favorite... is it the one where the second, identical hay truck goes through the mess the first one made? Or perhaps the 5th wheel camper that so carefully aeromodded it's roof?
Certainly the one that left it's entire cube wedged in there is in the TOP 3... maybe I need a TOP 5- can't leave out how nicely the "Two Men And A Truck" became "Two Doofs And A Convertible".
Yet another place where evidently the lesson is hard to learn.
