The Sax-A-Boom is a plastic toy saxophone that became an internet meme after clips of Jack Black energetically performing with it on stage were shared widely. Its intentionally tacky, over-the-top riffs fit short-form comedy perfectly, and editors began ripping short blasts as reusable stings. Like the Directed by Robert B Weide meme, it now signals an awkward or ironic ending, while creators alternate it with a club air horn for louder punchlines. Its appeal endures because the sound is instantly recognizable, silly, and short enough for memes, edits, and reaction clips.
