In this episode, Ed and Kara have a "pallet cleanser." Instead of massive wars with hundreds of thousands of people dying, in this episode no one dies (thankfully) but some buildings, both personal and city owned, don't get off so easily. Marvin Heemeyer was a relatively unassuming middle aged guy in Granby, Colorado who owned a reputable muffler shop. Overall Marvin was well liked and a talented welder who ran a snowmobile club. However, things changed when a dispute broke out about some auctioned property that Marvin won. Some high ranking members of the community may or may not have tried to stonewall Marvin's ambitions. There was also an issue as to where Marvin was going to store his poop...

Ultimately the entire escapade culminated in Marvin spending 18 months applying armor plating on a massive bulldozer bigger than a WWII German Tiger tank and Marvin sealing himself in it and proceeded to plough down as much of Granby, CO as possible! In a wacky 2.5 hour ordeal that involved nearly every member of law enforcement north of Denver, Marvin took his frustrations out on one building after another with his fortified bulldozer.
