Still, in college, I wrote some of my best papers when I was pulling all-nighters, and those felt a lot like this. My most epic one was a paper I wrote on Seven Samurai. I needed to re-watch the movie and take notes (as I do just before writing all my film papers), but I had to work until nine the night before it was due. I got home at 9:30, took a half hour to unwind, and put the movie on at 10:00. Of course, it's Kurosawa, so I didn't finish it until 2am. the paper was a minimum of eight pages, and was due in eight hours. Got that sucker done (I think it weighed in at 12 pages, because I'm stupid), and got an A. Reading through it after, I had no recollection of writing the last five pages, but whoever did it was an excellent writer.
So now I'm on four cups of coffee, about to go get my fifth, and remembering that I'm now old, and shouldn't do that kind of thing. So sad.
