The Calvin & Hobbes Search Engine is one of those things that you never really considered needing, but once you know it exists you immediately wonder how your life ever felt complete without it. I also like to call it by its other name, "The Greatest Use of Search Technology in the History of Ever." To get you started, I recommend searching "explore," "spaceman," and "booger."
And now, because this is one of the truly great gifts the internet has ever given us, here is every Calvin & Hobbes strip that ran on my birthday. Please to enjoy.
