I think I remember having to go to one pep rally as Freshman in High School, but it was nothing as bad as what Shen had to endure. Sheez, I think I'd a rather stayed at home that day and watched 6 hours of Barney and friends.
Anyway, after that year I always hung out with the crowd that ditched classes or the entire day of school for that matter. So we always saw a pep rally as an opportunity to ditch the rest of the day without getting caught.
Lol... Never really bought into the whole Hight School Spirit routine.
