From the people who brought the world (aka the Internet, aka "the real world") the Doug live-action movie trailer comes this one for the later Nickelodeon cartoon Hey Arnold!, by sketch group Drcoolsex. And it's just as eye-opening about the original series as the Doug trailer was. Hey Arnold! was about a kid with a football-shaped head to went to public school and got beat up by the neighborhood bully Helga. Now he's all grown up, and Helga seems to have turned over a new leaf and is, actually, pretty sweet and cute. Plus secretly psychotic. And if you grew up with these Nickelodeon shows, let this be a lesson that it could happen to you. To youuuuuuuuuuuu!
