<Li> Stephen Lea Sheppard as Harris Trinsky, a calm and sensible student who gives good advice to the other students . Harris is the Guru of the Geeks and often the Freaks . He is full of wisdom and accepts everyone for who they are, and often thinks the best of them, even the Freaks . First, he suggests to Sam and his friends on how to fight off Alan the bully, as well giving them advice for how to act around girls . Later, he talks with freak Daniel when Daniel asks him "Am I a loser?". Harris says that Daniel isn't a loser because he has sex, but if he wasn't having sex, it would definitely be debatable . Daniel surprises Harris by thanking him, and also compliments Harris's happy - with - himself approach to life . Harris is 15 years old . Harris is often seen carrying a Dungeons & Dragons book, and is also the Dungeon Master, much to Bill's dismay . Harris has a girlfriend named Judith throughout the show, who he often talks about even though she is only seen once . Harris is sarcastic in a dry way, and is well aware of it . </Li> <Li> Chauncey Leopardi as Alan White, the bully that picks on Sam, Neal, and Bill; the reason why is revealed in "Chokin' and Tokin"' after he nearly kills Bill in a practical joke gone wrong: he secretly enjoys science fiction and comic books, but was rejected by the geeks in his efforts to befriend them when they were younger . After mending fences with Bill, Alan is shown passing to Bill in basketball, despite Bill's lack of athleticism, and also calls Bill "the King" because he walked out of Coach Fredricks's class . </Li> <Li> Joanna García as Vicki Appleby, the bossy head cheerleader . Throughout most of the series, Vicki is short - tempered and impatient with everyone around her . Vicki lets her nice side out in rare moments on the show, such as talking to Eli about Three's Company and showing compassion over Bill's coma . When Bill and Vicki were stuck in a closet playing "Seven Minutes in Heaven", she was her typical (rude) self until Bill angrily told her she was a jerk and honestly said he didn't want to kiss her or have anything to do with her . Vicki then apologized and surprised both herself and Bill by having a nice conversation with him about The Jerk and then happily kissing him (after swearing him to secrecy, of course). </Li> <Li> Riley Smith as Todd Schellinger, Cindy's jock boyfriend . Todd is introduced as a mildly mysterious character . At first, you only see him through Sam or Cindy's eyes from a distance . It wasn't until Sam became a mascot that we see Todd and Cindy kiss . Later in the episode, Todd is shown to be a really nice person, talking to Sam as if they were friends . After Todd and Cindy break up and Sam and Cindy began dating, Todd confirms that he is a good guy when he bluntly tells Cindy he likes Sam and thinks he's a cool guy, and adds he's not going to fight Sam after she tries to manipulate him into a battle for her affections . </Li>
