Be careful when posting those links direct from the UMD. I don't think the organizations will notice, but just a word to the wise.
I spotted that clip with my alma mater. Damn. I know precisely on campus where they set up their pie booth too.
I remember my freshman year at Clemson, walking back to the dorms with a friend, maybe 3 weeks into class.... and this pickup truck drives by with about 8 gorgeous girls in the back, all wearing T-shirts and shorts... and covered in flour, honey, eggs, and whipped cream. Laughing hysterically. (Back then the "hazing" rules weren't enforced all that much.)
Years before I even knew what "WAM" was, it was a... formative experience.
