This is a perfect example of when Psych accomplishes the fine balance between keeping it funny and dabbling with some heavy stuff. 'Shawn has the Yips' is well written and well shot with an uncanny ability to jump from funny moment to a serious one seamlessly.
In this episode, Shawn tries to convince everyone after a shoot out at a local bar that it's an assassination attempt on one of them. The target as it turns out is Lassiter. Investigating the case Shawn and Gus team up with Juliet while Lassie sulks under protection before the bad guy is finally found.
This episode is a rare treat because it provides equal space to the entire cast. Everybody gets to play except for Shawn of course, who tries to deal with his hilarious mental block (thus the Yips in the title) of being unable to throw a proper catch even as he pieces the puzzle together.
Funny moments that stand out include Shawn's frantic elliptical workout fuelled by a fear that the machine is rigged to blow up should his heart beat rate come down. Only later does he found out, that the note was not a death threat but a 'motivation' tool left for him by Juliet. The whole elliptical version of 'Speed' is by far the funniest moment of the show.
