The Sax-A-Boom is a small toy saxophone that plays pre-recorded saxophone riffs when its buttons are pressed, and Jack Black turned it into a comedy prop through energetic live performances shared online. Clips of him dancing, grinning and squeezing out its squeaky solos spread widely on social video platforms, where fans trimmed the loudest moments into short sounds. The toy's contrast between its cheap plastic look and its surprisingly funky output keeps it funny, and the final, frantic section has become a favourite shorthand for over-the-top excitement.
