Happy Hey Day! (Cue Juniors freaking out and Seniors weeping silently). But this 1932 photo of the then-dubbed Cane March looks more like a funeral procession than a celebration. Maybe it's because they knew Penn didn't come up with the idea for Hey Day to begin with! That's right, our precious celebration was originally modeled after a similar idea at Syracuse University. But it also has evolved from a formal ceremony honoring the advancement of each class to a parade of raucous debauchery. Hats off for another reason to get drunk and procrastinate!
