"Well, hello there, little boy, don't be shy,
Step right up; I'm a reasonable guy!
Don't be frightened by the look in my eye,
I'm just your average evil meteor from out of the sky."
The Grim Adventures of Billy and Mandy: Little Rock of Horror wherein Billy befriends an alien meteor that eats everybody's brain to the tune of 'BRAINS!' by Voltaire (which can be found on his CD Boo Hoo).
