Who’s “that guy”? He would be the student who doesn’t actually know what’s going on in your class, but is pretty sure that he can still wing a good answer on the test. (OK, so sometimes gals do this, too.) The good news is that we needn’t worry any more about what’s to become of him—he’s going to be a sportscaster! Thanks, as always, to the good folks at www.xkcd.com for their willingness to share a chuckle. Oh, and enjoy your weekend.
