Mr. Darnell

Mr. Darnell was Independent Study teacher of Greg, Ricky Fisher and the other boys. He canceled the Independent Study classes for the remains of the school year for boys due to finding a list of completely profane words. He was arrested for hate crimes against minorities in The Long Haul. He is known as Mr. Lowry in the online version, but also went by the name Herbert the Pervert in a few scenes.
