I guess it’s safe to say this one is a meme…

Classic even. The original animation was made using Flash a long time ago…
Original music from The Buckwheat Boys – Peanut Butter Jelly Time.
Dancing banana animated gif is around for sometime, I dunno it’s origins, but I remember it spawned several other animated gifs as a joke… like a dancing carrot, cucumber, etc…
One of the YouTube videos credits this to Ryan Gancenia Etrata… dunno if that’s correct though.
