No, you're not still drunk from New Years Eve.
Toni Patanen, who has a total of one video uploaded to YouTube (spoilers: it is this one), made an ocarina out of a potato and played Sandstorm on it, just for us. Enjoy.
Toni, who goes by Pupsi, crafts his own ocarinas and sells them online. They aren't made from potatoes, though, they are - well, they are beautiful.
Hopefully this isn't the last we will see from this talented human.
