I can't write poems because

I can't write poems cause my english ain't that good,
And I can never seem to fit those preposiitons where they should.

I can't write poems cause my imagination's real bad,
And all my funny poems end up sad.

I can't write poems cause I don't know those many words,
And those I do, never seem to rhyme.

I can't write poems cause while I was reciting one the other day,
The cops came and took my poetic license away.

I can't write poems cause the last time i tried,
Half my friends went nuts, the other half died.

And after all this mindless ranting,
These pointless words,
This annoying chanting,
The top three reasons I can't write poems is
That before I can finish one,
I get bored....
