What was I thinking?

Tomorrow morning I have to teach two English 1020 classes before noon.  Tomorrow morning may be a two-cup coffee day.  Come to think of it, tomorrow morning may be ripe for a number of out of character activities, such as: vomiting in my new purse, actually forgetting my name, crying in front of two classes of college freshman/sophomores, getting drunk before 9am, actually forgetting coherent language, totally forgetting the way that "Young Goodman Brown," "Boys and Girls," "The Lost World," "Araby," and Erdrich's character, Lipsha all share the commonality of innocence lost to experience.  

I'm just a teensy bit nervous about this endeavor.  I keep imagining myself walking into the classroom and through some supernatural occurrence, they all know that I am horrifically under-qualified even to be supervising them for a period of 55 minutes.  It's a little like the dream where you're naked in pubic.  While I will surely remember to dress myself, what if they know I have no business being their temporary authority on American Literature?  This is only my second semester and I wasn't an English major.  I am the epitome of "fish out of water."  My second dreaded scenario is that they all have I.Q.'s infinitely higher than mine so that when they ask me questions, I have no. idea. how. to. answer.
