Only now does it occur to me... that when I just wrote about Grace Jones' ridiculous arrival via crate in the CHRISTMAS AT PEE WEE'S PLAYHOUSE SPECIAL, that it was, in fact, a common mode of transport. In the 1992 Eddie Murphy comedy BOOMERANG, a mysterious crate is helicoptered onto the docks of New York
Grace Jones being dragged around in a Roman chariot drawn by leather-bondage dudes.
Either this references an 80s concert gimmick I'm not familiar with, is an homage to the aforementioned PEE WEE special, or it represents the fulfillment of an incredibly specific contractual demand by Ms. Jones. Oh, the mysteries of the ages!
