If you haven't picked your nose and ate it yourself as a young child, I'm sure you knew someone who has. The difference is, it wasn't immortalized on the internet forever.
Here is a cute kid who is on tv and he picks and eats his boogers. He even goes back in for a second taste. Notice the kid with glasses not helping the kid by reminding him that he's on tv.
WARNING! Person who recorded the video didn't realize that you can turn your camera phone 90 degrees to the side to record in widescreen format.
