Mr. Huff is Greg's history teacher (during Rodrick Rules), who has only made one appearance so far in the book series, Rodrick Rules. He shares the same qualities as Mr. Litch - being authoritative and strict. Mr. Huff does not like Greg, and expects him to be as badly behaved as Rodrick even though that is only partially true.
- He has a very big head, which appears to be bigger than Frank Heffley's.
- In the online book, his name wasn't revealed and he was referred as "a teacher who had Rodrick in his class in middle school.".
- He was named Mr. Draybick in the movies.
