howl at the moon!

I've asked this question a few times, but no one seems to know what I'm talking about except for one other person. Do you ever feel different during the day time than you do at night? Am I a werewolf?

JUST LIKE A WEREWOLF

I AM FINE IN THE DAY

THEN THE SUN GOES DOWN

AND MY ENDS START TO FRAY

my palms start to itch

sanity is wearing thinner

fangs sprout out my gums     

all this happens before dinner

I DON'T MIND BEING JEKYLL

BUT IT'S HARD TO BE THE HYDE

CAN'T BEAT THE SYSTEM OF THE SKY

EVILS GROW IN THE NIGHTTIME

darkness falls above my head

and down goes the sun

i should expect this every night

the transformation has begun

NINE-O-CLOCK AND FULL OF FUR

MY GROWL'S GROAN AND DRONE

MY TEETH ARE SHARP AND SHINED

I'M READY TO DESTROY MY OWN

amazingly i'm the only one

to notice when i'm different

amazingly no one sees my fangs

their blindness is really quite sufficient

YOU'LL SEE 'DAY ME' AND 'NIGHT ME'

BUT YOU WON'T KNOW WHICH IS WHICH

WATCH WHEN THE MOON BEGINS TO RISE

AND YOU JUST MIGHT SEE ME START TO TWITCH.
