Nerdy in the best way possible, graduates over at Harvard Medical School and Harvard Dental School recently parodied the popular song “The Fox” by Norwegian comedy duo Ylvis. In their rendition, “The Spleen,” students at the Medical School ask the age-old question: what does the spleen do? Is it a back up tongue? A third eye? The world may never know.

The video was created for The 107th Annual Second Year Show by the Harvard Medical School and Harvard School of Dental Medicine class of 2016. The parody quickly went viral after it was posted to Youtube on December 8. Since then, it has reached over 1 million views in just five days. Another notable parody made this year by Harvard Medical School students is “The Gunner Song,” a spoof of Macklemore’s “Thrift Shop” that satirizes the stressful and overachieving lives of Med students. The class of 2014 did their own spoof for the Second Year Show two years ago with “Piss in My Pants,” a parody of Lonely Island’s “Jizz in My Pants.” We still may not know what the spleen does, but we do know that Med students can have some fun, too!
