I Have to Write a Poem

I have to write a poem but I really don't know how. So maybe I'll just make a rhyme with something dumb, like "cow."  Okay, I'll write about a cow, but that's so commonplace. I think I'll have to make her be... a cow from outer space!  My cow will need a helmet and a space suit and a ship. Of course, she'll keep a blaster in the holster on her hip.  She'll hurtle through the galaxy on meteoric flights to battle monkey aliens in huge karate fights.  She'll duel with laser sabers while avoiding lava spray to vanquish evil emperors and always save the day.  I hope the teacher likes my tale, "Amazing Astro Cow." Yes, that's the poem I will write as soon as I learn how.
