How not to move large quantities of furniture

The other day I was walking a dog when I saw a rather strange sight. Two men were sitting in a driveway in a beat-up old pickup waiting to turn onto the main road. On the back of this pickup truck was a massive pile of furniture. I quickly counted an armoire, four chairs, a table, and a dresser all balances precariously on top of each other. While a normal human being would have secured this unstable load in one way or another, these two men decided to take a laissez faire approach. They left the back of the pickup truck open and used a total of zero straps to fasten the pile. they were relying entirely on the static friction between the bed of the truck and the legs of the furniture. Unfortunately, as they peeles away, it became clear that they had never had the benefit of hearing Bill Nye say that "inertia is a property of matter." Perhaps the furniture wanted to stay at its old home, or perhaps it merely adhered to the laws of the physical universe, but it fell off the truck. It didn't even get out of the driveway. From what I could see, most of the furniture was still salvageable (save a missing leg or two from some of the chairs), but the lesson to be learned here is that you should have at least a basic understanding of physical properties if you want to be a mover in such a highly competitive field.
