Actual conversation with an English major:
Student, dubiously: "So...you're teaching the American Lit survey?"
Me, grinning: "Of course! Every spring!"
Student: "Doesn't anyone else teach it?"
Me, still grinning: "Nope. You're stuck with me. But it's my favorite class!"
Student, sighing heavily: "Then I guess I'll have to take it."
And I'm just exhausted enough that I can't tell whether he's joking.
