I thought I say everything. Every type of instrument, every type of performance, every variation of orchestration, every combination of song, singer, and speed. There was nothing you could do with the Super Mario theme song to impress me.
Well, I was happily wrong. I had assumed that only HUMAN ANIMALS would be performing the some.
This avian performance Is deservedly making the memetic rounds: the cockatoo has heard SMB so many times he/she (haven't checked the cloaca to be sure) really gets the jist of the tune. It'd be sweet if this was accidental, but still kind of amazing if done on purpose.
Update: There's already a response video! By a dog.
