What were the game changers for ABDC 1-3?

MTV Remote Control has a video of the performances they consider gamechangers for the first three seasons of America's Best Dance Crew. They include: JabbaWockeeZ - PYT; Super Cr3w - Get Up Offa that Thing (the Ninja dance); Fanny Pak - Get Ur Freak On; Beat Freaks - Freeze (the magic ball dance); and Quest - OrQuestra. These are performances that MTV Remote Control felt won permanent fans for the crews, positively changed fans' opinions about the crews' skills, and created enough goodwill to carry them closer to the finals.

I agree with some of these, but not others. Also, they do not include negative game changers - performances a crew made a mistake or disappointed the fans enough that they moved from the top to the middle/bottom for good. What would you pick for the positive and negative game changers for ABDC? To clarify -- please only discuss performances that changed the crew's momentum -- NOT their best or worst performances. If you've already commented on this elsewhere, I'll repaste it to this post, but feel free to add and stay in the conversation. Thanks, AND PLEASE KEEP THIS HATE-FREE!
