Yoyodyne Propulsion Systems in Grover's Mill, New Jersey, home of the Truncheon Bomber, is owned and operated the infamous Red Lectroids, sworn enemies of Buckaroo Banzai. Yoyodyne's CEO is John Bigboote' (Christopher Lloyd). Motto: "The Future Begins Tomorrow!"

Yoyodyne also appears in "The Crying of Lot 49" by Thomas Pynchon; presumably Earl Mac Rauch found it there for his screenplay "The Adventures of Buckaroo Banzai Across the 8th Dimension".
