The two answer words to this flat differ by only their second letter - as do STOUT and SHOUT. Can you replace them with words that make sense in the rhyme? Hint: STOUT can be replaced by a word that names a shape.

I'm a little teapot, short and STOUT.
Here is my handle, here is my spout.
I was made top-heavy; hear me out:
I tip over and out comes SHOUT.
