On nearly every episode of Psych, Dul Hill’s Burton “Gus” Guster would receive an embarrassing new nickname courtesy of his best friend and partner, Shawn Spencer (James Roday). It became almost a weekly tradition for Shawn to introduce Gus with a false – but funny – nickname that would usually earn him a frustrated look from Gus. The Psych Gus nicknames are one of the show’s highlights for fans, and fans often anxiously awaited the next nickname, plus the Gus reaction after Shawn sprung it on him.
