Half-baked ideas

These are ideas that I've come up with when Sean's not around to pester about them.

Oliver Kleauthzoff: sexual predator with X-ray specs that really work. Personality kind of like Roy.
Will Nixon: Nick Wilson.
episode about an evil RA, title: "Resident Evil"
somebody's ex (don't know if it's the same one as Larry's vampire ex) dies and later shows up as a ghost, basically being a harpy and haranguing the person about everything (alternate idea: she literally is a harpy)
Dr. Fist: rip-off of Faust
