A Break of a Lifetime

I think I now deserve my break, Before my brain turns into steak! My head is full of algebras, I have nightmares of Boyle's Law, Mughal rulers prance around While in class, I sleep sound. When I think of a little sac, I find a bundle on my back! Numbers shower like raindrops, When the teacher starts to talk! Homework, oh! homework times 10, Is what I get to do, again, I think I now deserve my break, Before my brain turns into steak!
