Moe is the prototypical bully character, "a six-year-old who shaves" who is always shoving Calvin against walls or onto the ground, demanding his lunch money and calling him "Twinky," or occasionally "Twinkie." Moe is the only regular character who speaks in an unusual font: his (frequently monosyllabic) dialogue is shown in crude, lower-case letters (probably the most intellectual word Moe has ever used is "spatula"). Watterson describes Moe as "every jerk I've ever known.[1]" While Rosalyn is frequently a match for Calvin's plans, and serves as, perhaps, his "match" on a more strategic and psychological front, Moe seems to be the only character capable of frustrating Calvin to the point of absolute resignation, and operates merely through brute force and physical coercion. Calvin's rare attempts to retaliate have mainly consisted of mocking Moe with words the bully can't understand: Moe: Gimme a quarter, Twinky. Calvin: Your simian countenance suggests a heritage unusually rich in species diversity. Moe: What? Calvin: Here you go. (flips a quarter to him; to audience) That was worth 25 cents. His mother is once shown calling the school to notify them on Moe's bullying, although it only made Moe return 25 cents to Calvin because some person had squealed on him and "it'll be a dark day if [he] ever [found] out who!" Another time in the strip, Hobbes is brought to school and Calvin successfully psyches Moe out by daring him to touch Hobbes (Calvin thinks Hobbes is scaring him; Moe thinks that the dare is some sort of trap). It could be noted that Moe is the only minor character in the strip who hurts Calvin without being provoked.
