Jess Ranard Underwear Run
An annual event started on 2012(?) by everyone's favorite MasterBaker, Jess Ranard, in honor of her birthday, body positivity, feminism, being queer, and JUST BEING GODDAMN AWESOME. Taking place on April 15th (or a day close to that) near midnight, attendees strip down to their underwear (or whatever they feel comfortable with) and run through several areas of campus, especially those occupied with people. It's especially fun on weekdays, because then you can watch all the people in the library go "wtf?" as you run by in your skivvies.
The 5th(?) Annual Jess Ranard Underwear Run of 2016 was notable for being the first incarnation not run by Jess herself, as she had graduated, finished post-bacc obligations, and moved to Washington D.C. Jess has since promised to organize another underwear run when she visits in May. :)
