I came to this link from my friend Lori Chance, author of Who Am I?, via her Facebook profile. Though I typically do not share these sort of things I felt obligated to share this one as it is so accurate. Xkcd have a number of other comics too, and I suggest you head on over and take a look, see if you like anything. I must admit my first temptation is to print this out and post at the computers of a few people I know.
