Wow. . . that's so . . . amazingly geeky

Go to newsweek.com

Type in the Super Contra cheat code (for those of you who don't know, it's
UP
UP
DOWN
DOWN
LEFT
RIGHT
LEFT
RIGHT
B
A
ENTER

Well, on Super Contra, it's "start", but a computer doesn't have a "start" button and does have an enter key, so there.)

EDIT TO ADD:

Seems like it's over. It changed the Newsweek page to a page all about the current zombie outbreak. But it looks like it's gone now.

However, check Wikipedia. They've got a list of other websites you can use the code on, too.
