One Knock, Two Knock, Three Knock, Four

One knock, two knock, three knock, four
How many hands are under the door

One knock, two knock, three knock, four,
How much blood has stained the floor

One knock, two knock, three knock, four
Do you hear that creepy roar

One knock, two knock, three knock, four
Can you solve this problem before

The devil they call the girl with one eye
Murders us all, and we all die
