Today and every December 14th is Monkey Day. Unlike most unofficial novelty holidays, this one has an actual website.
WMHD is a format-free/block programmed station run by the students at the Rose-Hulman Institute of Technology in Terre Haute, Indiana. Rose-Hulman's mascot is a pachyderm named Rosie but, for unknown reasons, WMHD wisely went with "The Monkey" branding rather than "The Elephant." Everybody loves monkeys.
