The scariest kinds of monsters are the ones inside of you.
For Halloween I guess. Have I ever mentioned that The Beast Within is my favorite episode?
I like to think that he's always fighting the instinct of all the animals he turns into, and that it probably freaks him out sometimes. Then add that lovely beast thing (people always call it "The Beast" but I find that kind of weird because it makes me think too much of Beauty and the Beast) and well... I know it would scare ME.
EDIT: OH LOOK this inspired a poem! Cool! =o [link]
