In-joke
The name of Keenan Wynn's character, Harvey Huntington Honeywagon III, is a bit of a Hollywood in-joke. On a location shoot, the "honeywagon" is the truck or trailer that contains toilet facilities.
Why "honeywagon"? Because it sounds better than "s---wagon," of course!
All the universe . . . or nothingness. Which shall it be, Passworthy? Which shall it be?
