Truck Driver

A gruff, anonymous voice behind the wheel, the Truck Driver pops up as one of Big Mouth's stray background gags — the kind of incidental adult figure who rumbles through a scene, drops a line, and disappears, embodying the show's habit of finding jokes in every corner of its world.

Nick Kroll treats even a throwaway role like this as a chance to build a whole voice and attitude from nothing, and that commitment is the joke. It's a small proof of how densely populated and generous Big Mouth's universe is, where nobody's too minor for a bit.
