Xbox Live: Talking Smack
This educational video is a 8-step program to becoming a Grade-A Asshole on Xbox Live. Lessons include "Smack Talking", "Corpsehumping" and "Spawn Camping". Even if you don't play Halo or Xbox Live, you can probably appreciate this sort of behavior if you have any sort of familiarity with the Internet.
I on the otherhand, play far too much Halo 2 on Xbox Live and so I found this video to be absolutely hilarious. It's true, people really are like this on Halo 2, which is why I have everyone's voices muted. I have no interest in hearing a 13 year old talk about having sexual intercourse with various family members of mine.
