Psych: Season 5, Episode 13

5 - 13: We'd Like to Thank the Academy

Thinking that Shawn and Gus' investigative tactics need work, Henry and Vick send them to the police academy for a three week crash course in police procedures, with an instructor (Ralph Macchio) who may not be suited for actual police work. Shawn can't help but get involved in a robbery case which also involves money laundering, and Vick learns that it's best to leave well enough alone.
