Psych: Let's Get Hairy (2009)

Summary: Stewart Grimbly stops into the Psych office asking Shawn and Gus to tie him up as best they can and watch him through the night. Stewart believes he is a werewolf and that he has already killed a lamb. With their usual mix of fear and skepticism, Shawn and Gus agree to bind Stewart and keep an eye on him, but they fall asleep. Stewart appears to escape, crashing through the Psych office window, and waking up in the woods next to two dead hunters.
