Mr. Ratburn (Nigel Charles Ratburn) is Arthur's third and fourth grade teacher. He attended Glenbrook where his passion for learning and teaching was guided by his teacher, Mr. Pryce-Jones. Various running gags involving Mr. Ratburn are of his strictness and love of homework, food, and dessert (especially cake). He usually drives a small red convertible but also bought a minivan and canoe online. In the Season 22 episode "Mr. Ratburn and the Special Someone", Mr. Ratburn is revealed to be gay when he marries his same-sex partner, Patrick, in a wedding attended by his students.
