Dm
Well hello there little boy.Now don't be shy.
A7
Step right up, I'm a reasonable guy.
Dm
Don't be frightened by the look in my eye.
Gm                                    A7
I'm just your average evil meteor from outta the sky.

Repeat intro

Dm
Well, I'm just shy and scared in this place
A7
I'm just a fish outta water from outer space
Dm
You can see that the trip has left me tired and drained
Gm                       A7
So why don't you be a pal...And bring me some brains

Dm
Go down to your neighbor's place
A7
See the dull expression on his face
Dm
You'd be doing him a favor if you brought him to me
Gm                               A7
He aint using his brain he's just watching TV!
Dm
Go down to Mr. McGee's
A7
He hasn't had a thought since '43.
Dm
His brain is the portrait of atrophy.
Gm                       A7
He ain't using it, why not give it to me?

Chorus:

Dm
BRAINS, BRAINS, I won't lie,
A7
I'll eat their brains 'til they're zombified.
Dm
Sure they might think it's deranged
Gm
But they won't give it a thought
A7
After I've eaten they're brain.
Dm
BRAINS, BRAINS, It's okay.
A7
It's not a matter if it isn't gray,
Dm
And if at first they thinks it's strange,
Gm
They won't think twice
A7
If they don't have a brain!
