A father tells his son the invention of the wheel was most important; to prove it, the two hipsters visit the inventor caveman Donald Duck. There follows a survey of the progress of transportation, a digression into the basics of gear ratios, a series of live-action dancers to various styles of music inside a giant jukebox, an illustration of the use of wheels in power generation and space satellites, etc. Ultimately, Donald decides he doesn't want the responsibility, but certainly someone else would take on the task.
