The other night Spittlefish runs around the house with a foam sword with a maniacal laugh and crazy eyes. When asked about his behavior, he says "I'm a psychopath".
I do wish I could find a copy of Scared Shrekless on DVD or YouTube. He does to a wonderful impersonation of Pinocchio in the "Shreksxorcist scene. "Voices...in my head... telling me what to dooooo". :)
