King Randor brings you gifts of food! Because, as Poe pointed out, he looks like BK's creepy mascot. And of course, "have it your way" was Burger King's slogan when this toon was made.
There's no dialogue in this one, because The King doesn't speak. The food he's carrying comes from Playmates' "World of Springfield" line - they were included with Krusty the Clown.
Knowing Mattel, if the Burger King did exist on Eternia, he'd be called "Bur-Gar" or something.
