Use BP's birthday number to open the box, and you get a note with a YouTube link, go to Google with the contents of the note, and it's a video. delucat posted the video two years ago with decrypted content. There is a link in the description below, click on it and it's a doctor's note from the doctor who once treated BP, and you can find out the rest for yourself.
This can be considered an Easter egg
