This video that is simply audio with subtitles is possibly one of the funniest things I've heard in a long time.
Someone calls this guy up and records his angry and very violent rants and then calls him back at a later date (having turned his first round of comments into a playable soundboard) and the guy doesn't know that he's talking and threatening to kill... himself.
So NSFW it's scary, don't play this at work or near your kids!!! :P
