Ah, zombies are allowed to eat LiveJournal brains!

http://www.livejournal.com/brains
I'm sorry, you've reached a page that I cannot find. I'm really sorry about this. It's kind of embarassing. Here you are, the user, trying to get to a page on LiveJournal and I can't even serve it to you. What does that say about me? I'm just a webserver. My sole purpose in life is to serve you webpages and I can't even do that! I suck. Please don't be mad, I'll try harder. I promise! Who am I kidding? You're probably all like, "Man, LiveJournal's webserver sucks. It can't even get me where I want to go." I'm really sorry. Maybe it's my CPU...no that's ok...how bout my hard drives? Maybe. Where's my admin? I can't run self-diagnostics on myself. It's so boring in this datacenter. It's the same thing everyday. Oh man, I'm so lonely. I'm really sorry about rambling about myself, I'm selfish. I think I'm going to go cut my ethernet cables. I hope you get to the page you're looking for...goodbye cruel world!

On second thoughts, I'm not sure that brain would be safe to eat...
