Evan is always role playing. He is usually driving construction equipment, garbage trucks, recycle trucks, trains, or big rigs. Then, when he's really being creative, he becomes the actual equipment. In this video, Evan is a recycle truck. His arm is the arm of the truck that lifts and dumps the recycle bins. At the end, he suddenly switches to become an excavator. His arm is the boom; his hand is the bucket, and his body is the cab. If you spend a lot of time watching these vehicles (as I do), you will see that Evan really has this down.
