>>76989290I'm talking about the sound at 1:01 and 1:36 in this video btw:
https://youtu.be/6kZoy1yflYEShows like Animaniacs, Freakazoid, Taz-Mania, Pinkie & The Brain, and maybe Tiny Toons, they all had this sound when something awkard happened, or there was a pause to get the joke, or there was a shot at a character's reaction face.
I don't think I ever heard it in any show after this one. For some reason I noticed it and associated it with this period of WB animation.
I kind of see "Sylvester and Tweety Mysteries" and "Pinky, Elmyra & the Brain" as the end of an era.
