Ha, great choice, Tiffany! — a parody of a parody! For those who are unfamiliar, Allan Sherman was the Weird Al Yankovic of the 1960s. I think "Hello Muddah, Hello Faddah" was the song that launched him to commercial fame. The long suffering melody had also been notably featured as the ballet of the hippos in Disney's movie Fantasia from 1940.
Although officially it's the ballet Dance of the Hours from the Opera "La Gioconda" by Amilcare Ponchielli, whenever I hear it I get a bizarre mental image of cartoon animals dancing to kids singing about nightmare summer camp. Tiff, you've now added another mental layer!
