The tune comes from Bananaphone, a children's song by Canadian singer Raffi released on his 1994 album of the same name, built around the joke of making a phone call on a banana. The simple chorus and playful premise made it easy to quote, and short clips of the song later spread through memes, reaction videos and phone-themed edits. Its brevity helps it survive as a quick gag, because listeners recognise the melody in a second and immediately get the joke without needing the full song.
