parody of I'm Only Happy When It Rains in song parodies

I'm only happy when there's brains
I'm only happy when it's me who ate it
the only way that I am satiated
I'm only happy when there's brains
you know I love the stuff inside your head
the only fuel there is for the undead
I'm only happy when there's brains

pour your viscera down
neurocircuitry inside me
pour your viscera down
neurocircuitry inside me

I'm only happy when there's brains
I feel good when things are going splatter
watch the glisten of the gray gray matter
I'm only happy when there's brains

I only stalk by the dark
the noonday sun plays havok on my eyes
the full moon's light better helps me disguise
I'm only happy when there's brains
you'll get the message by the time I'm through
disemboweling and consuming you
I'm only happy when there's brains

pour your viscera down, pour your viscera down
neurocircuitry inside me, pour your viscera down
pour your viscera down, pour your viscera down
neurocircuitry inside me, pour your viscera down
pour your viscera down, pour your viscera down
neurocircuitry inside me, pour your viscera down
pour your viscera down, pour
and when I get hungry
I just don't like to share

I'm only happy when there's brains
you want to hear about my new obsession
they help me sustain this strange resurrection
neurocircuitry inside me
I'm only happy when there's brains
neurocircuitry inside me
I'm only happy when there's brains
neurocircuitry inside me
I'm only happy when there's brains
