Psych: Every Nickname Shawn Has For Gus

In nearly every episode of Psych, Dulé 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. The Psych Gus nicknames are one of the show's highlights for fans, who often anxiously awaited the next nickname, plus the Gus reaction after Shawn sprung it on him. Psych stars Roday and Hill as Shawn and Gus, childhood best friends who become private detectives.
