And then, if you succeed in not getting bored with the mindless task and actually destroy both statues, the screen will show a code that, once decrypted, turns out to be a toll-free phone number -- the game is from 2005, but the phone was still working as recently as 2010 (although for all we know it might be a Taco Bell by now). So what happens if you call there? You get a recorded message from Kratos himself, who congratulates you for finding the secret:
Halfway through the message, though, the call is hijacked by the game's writer and director, David Jaffe, much to Kratos' confusion and irritation. Jaffe starts off praising you for wasting your time whaling on those statues for an eternity, but then decides you actually "kinda suck" if you simply looked the secret up online, or had it carelessly spoiled for you by some comedy website. Considering that most sane players are likely to whack the statues a few times, shrug their shoulders and move on to the ending, anyone who did find it on their own probably spent the entire game pounding on every piece of scenery for an hour.
Much like Kratos himself. Hiyooooo!
