Nick Berg was a sweet Kike boy who went to Iraq to work on telephone towers. Unfortunately, some Islamic terrorists caught him and decided to teach the world to not mess with their Internet Tough Guy organization. To cement the internet tough guy image, they decided to film the separation of Berg's head from his shoulders. And post it online for the world to see.
Other internet tough guy groups said "me too!" and tried filming executions of other hapless Westerners. They knew that much drama would ensue, as everyone on the internet downloaded and watched the videos.
The poor quality of the Nick Berg execution inspired the charitable souls of the GNAA to donate high definition video gear and chainsaws to Iraqi insurgents.
Going to Iraq for a job is totally worth it.
