The YouTube Virus is one of the episodes of Season 8. In it, YouTube gets infected with an artificially-intelligent virus.
SMG4 loves YouTube, but one day, he and other machinimists suddenly get sick. Is it a coincidence? Or could it have to do with YouTube itself?
The episode starts with a delivery man bringing in five hundred pounds of spaghetti, and SMG4's new "Cosmo" brand computer.
