Miaow

You must never hold me to my words
- Never say "then you said that
And now you say this". See?
Now I tell you more about birds

There is a bad one called the rat-buzzard
Because he feeds on rats
Because he's bad
It's made hard for him to catch them

He can only say one word
And that sounds like a cat's "miaow".
So when the buzzard says "miaow",
The rats run away and hide
