Psych

What, no dancing dwarf?  Psych pays homage to the 20th anniversary of Twin Peaks with "Dual Spires," a supersize episode that finds kooky crimebusters Shawn (James Roday) and Gus (Dule Hill) investigating the murder of a high-school girl in a quaint mountain town.  It's David Lynch all the way — from the corpse wrapped in plastic to the guest cast, which includes Peaks veterans Sheryl Lee, Sherilyn Fenn, Dana Ashbrook, Robyn Lively, Lenny Von Dohlen, Ray Wise and even "Log Lady" Catherine Coulson.

"This reunion was a great gift because a lot of us had lost touch — we had a blast!" says Lee (original corpse Laura Palmer).  Psych creator Steve Franks says he's wanted to do this tribute for years. "Twin Peaks was so bold and influential and spat in the face of everything we thought about television," notes the executive producer.  "We all bow at the altar of Lynch.  Nothing would make us more depressed than him hating this episode!"

Psych airs Wednesdays at 10/9c on USA
