Mahoot is the very challenged student of the class. He sometimes stares blankly and often says "What?" When the bell rings, he does not always leave the class. He has a cousin named Darryl, who visited the school once and is even dumber than Mahoot.
In "Good Will Mahoot," Mahoot only once speaks in full sentences when Dawn accidentally says, "What" during her part, but goes back to his catchphrase when Mrs. Munger tells him to say it again.
