Contra
Who could forget the video game Contra? You can fight your way through each level to defeat the alien invasion. Will you be victorious? If all else fails you can always use the Contra code. The one code that everyone memorized as a kid and will always remember. Just hit up up down down left right left right to give yourself more lives.
If only those kinds of codes worked in our everyday lives. Life would be so much easier. We could constantly give ourselves more chances to complete our missions until we get them right. There are a few things I wish I could have had thirty attempts to get right.
