James Roday, Dule Hill James Roday, Dule Hill

If you can spot the vampire reference in the line "Let the right ones in, buddy" — from tonight's enjoyably spoofy episode of USA Network's Psych (10/9c) — then you're in for a real treat, as Halloween is played for laughs (more often than not on purpose) on a variety of tonight's shows.

The cleverest might be Psych's guest star-studded comic mystery (titled "This Episode Sucks"), in which a body drained of blood leads Shawn and Gus to deduce a vampire is on the loose. Could said fiend be the new mystery lady in Lassiter's life? She's played by original-movie Buffy Kristy Swanson, so anything's possible. Also making cameos: TV-Buffy alum Tom Lenk and eternal where-are-they-now curiosity Corey Feldman. But the real pleasure here is in watching James Roday (who co-wrote and directed the episode) and Dulé Hill work their way through a midnight movie marathon's worth of horror references, none funnier than when Gus is repeatedly mistaken as Count Chocula when it's so obvious (to him and Shawn, anyway) that he's dressed as the "iconic" Blacula. There's a pretty good Carrie joke as well. (Which reminds me: With Saturday Night Live in repeats this weekend, I sense a DVD horror-movie-a-thon in my immediate future.)
