900 is the 5th of 22 episodes in The '00s. Steve and Kevin get a new game called Tony Hawk's Pro Skater 3 that just recently came out not too long ago. They end up playing the game, and Kevin converts a special skateboarding trick in the game simply referred to as the 900. It's a skateboarding trick where you do a 900 degree spin in the air which is extremely difficult to do. Afterwards, Kevin brags to the whole group of friends that nobody can convert the 900 like he just did, and that he's the grown-up of the whole gang since he's the oldest child character.
