That was one of the best episodes ever! Definitely one of the funniest.

I want to watch it again soon just so I can hear all the great lines again -- on a first viewing they come at you so fast you can't always enjoy them fully!
Shawn is a complete spaz and I love it.

And I love all the interesting little details and twists of the relationships -- Shawn/Gus, Shawn/Juliet ("Roosters don't cackle!"), Shawn/Henry/Lassiter (who saw THAT coming??), etc.
I sound like a total shill, so I'll point out just three flaws.

One, I REALLY wanted to see Shawn and Gus in the minefield. Two, the Psychout scene looked like a deleted scene -- wish they'd left it in. Three, the killer was easy to spot this time.
But I'm enjoying this show so much. I guess I've been watching dramas (not always well made dramas) for far too long, because watching TV was starting to feel like drowning in angst and melodrama. I was so ready for a show like this.
