Before Shia LaBeouf was playing a suited-up trader in Wall Street: Money Never Sleeps, he spent years of his life playing cute but awkward kids and adolescents. Back in 2000, he was one of the many soon-to-be-stars to appear on the cult favorite series Freaks and Geeks. Watch as poor Shia plays the school mascot (in a wig!) and gets teased when his extracurricular activity goes awry. Bonus: keep a lookout for JoAnna Garcia as a mean girl cheerleader.
