Three little pigs.
The three little pigs they were very frightened, they knew the wolf wanted to eat them. And that was very, very true. The wolf had not eaten all day and he had worked up a large appetite chasing the pigs around and now he could smell all three of them inside and he knew that the three little pigs would make a lovely feast.
So the wolf knocked on the door and said: Little pigs! Little pigs! Let me in! Let me in!
But the little pigs saw the wolf's narrow eyes through the keyhole, so they answered back:
No! No! No!
