I was looking at people who post comments on Youtube and I noticed and I ran into this one under a Canadian Idiot (by Wierd Al, Yankovic) by a shpannah and it says this...

WHEN U R READING THIS DONT STOP OR SOMETHING BAD WILL HAPPEN MY NAME IS SUMMER I AM 15 YEARS OLD i have BLONDE HAIR , SCARS no NOSE OR EARS I AM DEAD IF U DONT COPY THIS JUS LIKE FROM THE RING COPY N POST THIS ON 5 MORE SITES OR I WILL APPEAR ONE CREEPY NIGHT WEN UR NOT ExPECTING IT BY YOUR BED WITH A NIFE AND KILL U THIS IS NO JOKE SUMMET ING GOOD WILL HAPPEN TO U IF YOU POST THIS ON 5 MORE FLASH BOXES

I'd like to say that this is the first post I have seen of this kind on Youtube, but unfortunatly it is not. Also, it's not like anybody ever posts to say that they are crazy. They just shake it off and move on.
I wonder if any of you have seen these types of posts on Youtube and have felt the same way that I have?
