Not a cowboy
Francis Lax voiced Optimus Prime and Bumblebee in the French-dub version of the G1 Cartoon.
He was also the French voice for Magnum, P.I., Han Solo in the Star Wars trilogy, and that hippie in Scooby-Doo. Bumblebee kinda sounded like him, actually. Weird.
Instead of "Autobots, transform and roll out," he simply said, "Autobot, Transformation." Laaame.
