Who Told XKCD?

One of my reoccuring dreams is that I'm back in college or high school and one day, I look at my daily planner, and discover that I've been registered for a class that I haven't been attending. I attended the first few meetings, just enough so that I wasn't automatically dropped from the class, then proceeded to miss the rest of the semester. Now, with a week to go, I realize my error and try to figure out how I completely blocked out my enrolling in BUS 410.

Well, apparently I'm not the only one as the guys from XKCD Web-Comic have stolen the dream right out of my...dreams.
