Because for every weird thing in the world, a Wikipedia article exists about it.

The Inerrobang:

The interrobang, interabang, or quesclamation mark, ‽, is a nonstandard English-language punctuation mark intended to combine the functions of the question mark (also called the interrogative point) and the exclamation mark or exclamation point (known in printers' jargon as the bang).

The name kind of reminds me of the McGangbang, which is basically a McDouble with a McChicken stuffed in between the two patties.  Delicious heart clogging, dollar menu goodness.

Godwin's Law

Godwin's law (also known as Godwin's Rule of Nazi Analogies or Godwin's Law of Nazi Analogies) is a humorous observation made by Mike Godwin in 1989 which has become an Internet adage. It states: "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." In other words, Godwin put forth the sarcastic observation that, given enough time, all discussions—regardless of topic or scope—inevitably end up being about Hitler and the Nazis.

I can attest to this, especially on random internet forums. In my Small Group Communications class, we were doing a presentation on Leadership, and guess who came up? Even in my psych class, there was a discussion about disorders making people do extreme stuff, such as wanting to exterminate races and stuff. Crazy, right?
