I'm a poet

I haven't writ
In quite a bit.
So here I'll sit
And think on it.

I thunk about it
And I doubt it.
To write's a pain
And quite inane.
Darn my brain,
I'm quite insane.
I try to write
But have the blight.
I cannot write
And so, in spite
Of what I thunk
I'll only plunk
One word or two,
(no more than two)
Then say adieu.
So here's the words:

"Sacre bleu!"

Aaron, did I spell that right?
Or should I say,
To save the day,
"Oh golly, Dang!
Misspelled again!"
