Ode to the Boy in Maya's Class

One of Maya's fellow students was a McCain supporter. He's disappointed in the way the election turned out. His solution? Write limericks rhyming Obama with Osama, of course. So, I helped Maya with a rebuttal:

There once was a boy in my class
Whose rhymes were really quite crass
He thought he was clever
But all he was ever
Was a really big pain in the butt
