a list of 25 college traditions that "toe the line of insanity." Vassar's Serenading has made the list, although the description of throwing condiments is a bit outdated.
Other traditions listed include streaking and primal screams, both of which Vassar also has covered.
It seems that Serenading is rather well known even outside of the Vassar bubble. Back in 2007, OTR named the event the craziest college tradition.
