You know the moment I'm talking about-- the one where a mystery has been cleared up for you. I usually experience after I've been trying 1023 permutations of the wrong way to do something. Maybe you receive a cryptic email from tech-support that tangentially applies to the question at hand, but seems like an accident. Perhaps you've wondered why everyone was going the wrong way on a street except you. You might have even wondered what compelled that person sitting next to you to eat your cookies.

Feel free to pass it around so everyone can share the moment :)
