THUD is a spoof of THX in the direct-to-video movie, "Tiny Toon Adventures: How I Spent My Vacation". The logo starts by the sound of an orchestra warm-up with a conductor's hand and baton, then it suddenly fades into the THUD logo zooming in before displaying "The audience is now deaf" with the announcer saying it. It's Deep Note is disjointed, while straight at the end, THX had a straight and rising Deep Note. The audience is usually blown away by the sound, as at the end, some of the audience has collapsed and out of their seats. Shirley refuses the "free snacks" that Fowlmouth brought her before she displays a grossed-out face. After that, at the start of the logo, Shirley and the rest of the audience (Except for Fowlmouth) ducks under a seat with various head equipment (Gas mask, helmet, etc.).
