Bugs Bunny first appeared in Warner Bros cartoons in 1940 and became the central star of the Looney Tunes and Merrie Melodies shorts. The short, jaunty orchestral theme music linked to those cartoons became instantly recognisable through decades of theatrical screenings and television reruns. As the shorts moved online, creators clipped the opening music into a standalone sound for entrances and throwback jokes. Its lasting appeal comes from that shared recognition, letting a few seconds of music summon an entire era of Saturday morning cartoons.
