Almost Worth Knowing: You Have To Try This...

"Up, Up, Down, Down, Left, Right, Left, Right, B, A" is as iconic as the original Nintendo Entertainment System. If you don't know what I'm talking about, I suspect that you are either a girl or under the age of 20.

Known officially as the Konami Code, it is perhaps most well recognized in North America as being the code that made Contra playable (in an otherwise impossibly difficult game, the code granted the player character 30 lives instead of just 3). The code was originally used in Konami's Gradius franchise, and can be found in many games by Konami, as well as other manufacturers.

Video games, however, are not the only place that the code can be found.

THAT'S RIGHT!!! Apparently, even websites can employ cheat codes. If you enter the code on our favorite social networking website, Facebook, you can achieve some cool lens flare and word blur effects while typing and scrolling. The code is entered using the keyboard, followed by the Enter Key twice (using your keyboard, press Up, Up, Down, Down, Left, Right, Left, Right, B, A, Enter, Enter). I only tried it on my profile page, where my wall is, so I don't know if it works everywhere. Still... pretty effin' cool.

Moreover, the same code works on Google Reader (for those of you who use that to read my blog) causing a different theme to appear in the side panel, as well as altering the number of unread messages to 30. You can simply input the code again to change it back to normal. If that's still not enough for you, please check out this Wikipedia page, for a larger list of games and websites that also use the code.

Finally, if there's anyone out there who knows how to program the HTML code that makes this work, I would love to know it. Random website cheat codes sounds like an awesome feature to implement in AlmostWorthKnowing.com.

Challenge: Here's the first challenge issued in a long time, and, as far as challenges go, it's a pretty hard one. Without use of the Internets, please tell me the codes used in the popular PC game, Doom, that allowed the player access to full ammo and weapons or that granted the player invincibility, also known as God-mode.
