Gus as a suited-up lounge singer? Shawn with a pencil-thin mustache? Oh yes, Psych fans, that’s all happening tonight.
TVLine has an exclusive first look at the time-traveling, mind-boggling episode (9/8c on USA), in which Lassiter attempts to solve the decades-old murder of the mayor’s uncle in the hopes of being promoted to Chief of Police.
Juliet’s relationship with Shawn is also tested in the episode, but we promise it has nothing to do with him slapping her on the butt in this clip.
Following tonight’s episode, only four more cases remain until Psych airs its series finale March 26.
