In other news, I swear Randall Munroe over at xkcd is totally stealing my ideas, and then re-imagining them to make them 100% better. Take a look at this xkcd strip. See the similarity to thesethreestrips? Heck, there's even a time travel joke in his unixkcd interface! Harrumph.
Aww, who am I kidding. Randall, I can't stay angry at you.
