"Alright, kids, today we're learning what happened during the French Revolution, as requested by your teacher in the instructions she gave me."
"Um...but Miss Eudomius, you just lit the history textbook on fire and threw it out the window. Don't you think that'll make it a little bit, oh, I don't know, difficult to learn what happened if we no longer have the book?"
"No, it won't. I was there during the French Revolution, and I almost got beheaded, but I had a certain less-than-wealthy friend who somehow managed to pull me out in time. I am an immortal, Mr. Varela. Now please just take a sheet of loose leaf paper out for notes, and listen closely as I give the lecture."
