Keith is very very cool but I hate to see what happens when he tries to have a calm and rational sit-down with Zack. This MUST be where the infamous "zack attack and his fifty friends" speech comes into play. Zack is so annoying. It really goes to show that physical appearance can change immediately depending on personality.
(Hee. Off-note – wasn’t “Zack Attack” the name of Zack’s band on Saved by the Bell? )
