An Exorcise in Poetry

Knock, knock.
Aw, c’mon. I’m trying to sleep.
Knock, knock.
And I hate Knock-knock jokes.
Knock, knock.
Okay. Who’s there?
Nobody.
Well, go away. I’m trying to sleep.
I’m supposed to be a ghost, see?
I don’t believe in ghosts.
You’re supposed to say ‘Yikes’ or something.
Yikes or something. Now drop dead!
I am already dead.
Then knock it off, I’m trying to sleep.
