Yep, really. This song was supposedly written by to help the Detroit zoo get a hippo, which they did, back in 1953. Random. And they still play the song every Christmas...and probably always will. Interesting little fact. And in fact, the hippo was presented to the little girl, Gayla Peevey, who sang the song and she gave it over to the zoo. Seriously guys? What did you think she was gonna do with it? Ride it to school every morning?
