The Zack Files - Season 2 Episode 2 Searching for Zack Greenburg
Overview: Zack has a record of the lowest mark at Horace Hyde White, producing an F-minus on a physics quiz, so when Spencer downloaded an internet physics tutorial to help Zack's intelligence, Zack's headphones were plugged into the modem, making Zack a genius. Spencer's goal was to win the Physics competition, but when Zack came in, he was even better than Spence at Science. This almost led to a break up of friendship.
