You guys made me search the SMF source..
'posts' => $profile['posts'] > 100000 ? $txt[683] : ($profile['posts'] == 1337 ? 'leet' : comma_format($profile['posts'])),
So there IS actually another easter egg, just not that boob-thing lol. Upon more than 100.000 posts you get the following permanent post count:
$txt[683] = 'I am a geek!!';
Seems fair.
