Remember the Nintendo game Contra from years ago? Facebook has decided to use the Contra secret code as a special easter egg for users. When you visit the site and enter the code up, up, down, down, left, right, left, right, b, a, enter, you will be presented with a screen flare that pops up on the page. I’ve embedded a video demo below which shows me entering the code and achieving the desired result.
The code needs to be entered on any page that you’d like the effect to take place but it appears to work anywhere on the site. Earlier this week, ESPN.com used the same code to randomly display unicorns any time a person clicked on the page. It was a pretty funny trick but it disappeared after a few hours. Facebook is known for their numerous easter eggs and this appears to be the most recent addition.
It’s a funny trick but one has to wonder what other easter eggs are lying around the site. For those unaware of the concept of Easter eggs, they are small code modifications on a site left by a developer meant to entertain those users (or the developers) who are exploring random locations of that site.
I previously wrote about other Easter Eggs on Facebook’s site. Most recently I posted about a few tricks found in Facebook photos. Interestingly enough those Easter Eggs still exist and there continues to be more found every once in a while.

ESPN.com did this same thing 2 weeks ago. Come on Facebook, at least be original.
That is great! I loved that game.
You should check http://konamicodesites.com
IE only. Doesn’t appear to work in FireFox.
I did the code and was able to advance to the final level..
what a load of rubbish.. this is the nost retarded thing ive come across
@Mike, it does indeed work with firefox, just did it with no problems (you do have to manipulate the screen though, scroll, type anything like that)
HOW DO YOU GET RID OF IT!!!!!!
Balls. Tried it in IE 8. Tried it in Firefox 3.5 and I can’t get it to appear at all. Is this a hoax, with random ppl claiming it works when it doesnt?
how do we get rid of it??
OK, so this easter egg DOES work, at least in IE8. For those who haven’t tried it, it’s really not as cool as you think and it gets old fast. Redoing the code will not get rid of it, I had to log out and then log back in to finally make it STOP.
To get rid of it - simply refresh the page. =)
It worked for me, using Google Chrome on my eeePC
Not a fake, you’re either doing it wrong or have an incompatible browser.
wayne kerr - Seriously? All the trash on the internet and THIS is the single lamest thing you have stumbled across? Impressive.
Well, it turned off, but now my computer actually SAYS everything I do. How do you get that to stop??
ummm ya i thought it was funny that this thing happened so ya if you guys dont shut the fuck up about how you think this is gay then im going to go to your house and kill your father and rape your mother and eat your babys in front of you then ill tie you up to a tree and light it on fire
for any1 who have problems with that just follow this
up up down down left right left right B A then hit ENTER
^^ for it to stop simply refresh the page..
hope it helps ^_^

See the thing is you have to do it reasonably fast
