There are probably characters creepier than Terry Long, but he's so ill-conceived that he gives off bad vibes. Like, the age difference might not have seemed so bad if they hadn't made him a professor with a gaggle of female students Donna's age. (And WTF is up with them throwing their panties at him? No one needs an A that badly.) It's like, "Dude...why are you hanging out with teenagers, again?"
