We know, you've been shivering with antici...pation while waiting to get to this guest star. Obviously, we could never leave out Tim Curry. He basically played Psych's version of Simon Cowell in season two's "American Duos," which saw Shawn and Gus entering a singing competition to figure out who was trying to murder Curry's character, Nigel St. Nigel. We will probably never get the image of Tim Curry wearing Henry's little white robe out of our heads, but there are also much worse (better?) images of Tim Curry burned into our minds forever, so it's probably OK.
