The daughter of one of my former co-workers, who is 6 I think, just started posting Let's Play videos on Youtube. This has to be the funniest thing I've seen. The video opens up with "Welcome to Minecraft. Today I will show you how...to burn a dog."

Just keep it clean if you decide to comment. Her parents monitor their kids account and won't hesitate to contact Youtube. Not that I'm implying that there is someone on these I'm worried about. Also, if you don't like a child's sense of humor, which can be fairly disturbing at times, you have been warned.
