Laughed my ass off.
Right behind you!
Epic, but where did it come from I wonder?
Leaked from valve, it says.
Valve uploaded it on their YouTube channel, marked it as private, then deleted it some hours later. YouTubers couldn’t see it, but the people viewing the iPhone/iPod Touch version of the YouTube site could, despite of it being private, for some security fault reason with the mobile version of said site. You can guess what happened after that.
Basically - blame it on Apple and the fuckheads that run YouTube.
Not Valve’s fault.
Sauce, mang?

Via Facepunch. I believe there was also a thread in the official TF2 forums, but it’s a friggin’ clusterfuck of threads now that the video is out, I’d be damned if I could find it now.

Thank you sir. HD version is probably coming up in the next Spyper update day.
“Your Mother”

I lol’d… Hard.
That link doesn’t go to the Facepunch thread… >.< I’ve messed up the editing. Anyway, it’s not the original thread, just a reference to CSNation, but I believe Facepunch was the one where it all happened, the Steam thread does have a link to the topic where the actual act of leaking is mentioned, somewhere in those +40 pages.
Thing that bothers me is what’s gonna be Valve’s move. Do they just admit it was leaked, and say “Well, shit happens, here’s the HD version!”, or do they pretend they did it on purpose? Because, I’ve come to the realization that an iPhone security exploit could be overlooked and they might’ve not done it intentionally, as some of the speculation suggested. Then again, they did upload it to YouTube just to delete it after a couple of hours.
It was either intentional, or somebody fucked up. Seriously.
i knew who it was from the start, since he didnt know the code for the dors ;D
WHAT? It was obvious

The best “Meet The” video so far. The moment the Soldier shot the BLU Spy actually made me jump in fright. Leaked on purpose or not, it stole the “My Favorite TF2 Video Ever” title from Meet The Soldier.
This. 
Fucking hilarious though. Valve are becoming brilliant at animated shorts.
Aww come on, didn’t the [color=White]The Sandman fool you? Plus, that was so the[color=White] Scout’s style there, why would he bother with the code? He needs to go there FAST! Plus, the Spy put up a great show, you have to admit.
Wow, there is usually more hate for leakers on this forum. This is a rare change. 
I realised at first then I changed my mind to spy, but when he pointed to himself as a possible culprit, I chose scout again.
Yup, I think that’s what fooled me. And the [COLOR=‘White’]pictures were really unexpected.
Although I have to admit, the fact that in-game voice clips were used several times instead of brand-new lines was kinda annoying. At least for me.
VALVe: “Spy’s sappin’ my media…”
Now, I know I’m very anti-game movie but…
That was the best “Meet the ___” Video ever
“And now he’s here to f**** us!”
Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
