Dude, it's not like you posted this late. THIS IS LIKE POSTING ALL YOUR BASE IS BELONG TO US video now and expect us to have never seen it before. This has been around for 6 months now. There are people imitating it and making their own videos. That fucker has been on the TODAY SHOW because of this thing.
You aren't late, you're ANCIENT! Even casual, non-hardcore internet people who just spend their time online on MSN chatting to their buddies knew of this before you.
A funny little parody
