Mr. Lynch (Voiced by Ron Lynch)—Brendon and Melissa’s teacher who, later in the show, also becomes their interim principal. He is referred to by two different first names (Ronald and Donald) in the same episode ("Broken Dreams"). He is often at odds with McGuirk, who intensely dislikes Lynch but sometimes befriends him. Lynch is a somewhat pretentious person; he insists on pronouncing "Mexico" meh-hee-co. Lynch would like to believe that he is fluent in Spanish, but makes numerous errors in both grammar and vocabulary, particularly while intoxicated. He is the owner of numerous oddly-named cats (because he is obviously single) (the cats' names are: Anjelico, Fernilico, Moo-moo, Señor Twiginsky, and Sanchi-San, as seen the episode Honkey Magoo), and once suffered a breakdown when Brendon accidentally freed them all. Lynch also has a cat coffee mug and cat underwear, as seen in "Everybody's Entitled to My Opinion." A subtle, visual running gag in the last season is that he is secretly a cat-themed superhero, inspired from the previous season finale; this joke is usually relayed in the form of a newspaper headline in the background; the pictures accompanying the articles show a man in a cat costume very similar to the one Lynch dons in "Coffins and Cradles" and the cat costume is shown in a glass case in his office in "Everybody's Entitled to My Opinion".
