XKCD webcomic turns 10 years old today

Combine math, science, romance and crudely-drawn stick figures and you'll get something approximating XKCD, a webcomic that's celebrating its 10th anniversary today. Created by Randall Munroe (a former NASA roboticist and programmer) in 2005, the strip doesn't seem like much -- after all, it's just stick figures -- but it's the combination of smarts, humor and a touch of whimsy that make XKCD one of the most beloved comics on the web. It's even helped Munroe develop a successful publishing career, with his What If book (which offers "serious scientific answers to absurd hypothetical questions") rocketing to the top of Amazon's bestseller list in just 24 hours. Widely shared and celebrated not just among us nerds but also anyone who appreciates a good joke, XKCD has certainly gained cult status on the internet and beyond. To celebrate that, we've compiled a gallery of our favorite XKCD strips, which you can peruse below. If you've got your favorites, let us know in the comments too.
