Whither Breath?

Has anyone ever written a poem in which all the lines rhyme because it's the same word?  I wanted to write a trifling little piece of doggerel about "breath" but there aren't many words that rhyme perfectly with breath: death, meth, Beth & Seth are the only ones I can think of.  The others are "near-rhymes" like "breast," relying on rhyming of the internal vowel sounds rather than the ending sounds (is that assonance?).

Anyway, I wrote a poem about breath that just rhymed breath with breath all the way through.  It went like this:

Because I could not stop for breath
I had to go & shop for breath.
Said she, "I see you're spilling breath."
Said I, "Better than killing breath."
Said she, "You should perhaps change your breath."
Such statements can derange your breath!
Still I worried about my breath.
Could I do without my breath?
I think I'll have to mint my breath.
A sweet taste just to tint my breath.
But what if I can't fix my breath?
Find something with which to mix my breath?
Seriously, what goes good with breath?
Like fire goes with wood, with breath?
I don't want chewing gummy breath.
I don't want Jamaican rummy breath.
I don't want super cheesy breath,
Lemon squeezy easy-peasy breath.
Since I can't have nothing breath,
I need to work on bluffing breath.
Said she, "You think too much of breath.
I even think that you love breath!"
Said I, "Until you tasted my breath,
I would have said I wasted my breath."
Said she, "Come here!" & took my breath
& with her lips she shook my breath.

I understand that I made the phrases all rhyme, not just the last words.  I couldn't help myself.

The first line is of course an Emily Dickinson riff.  I couldn't help myself there, either.
