Why is everyone saying Kristen Stewart and Robert Pattinson are dead?

Why is everyone saying Kristen Stewart and Robert Pattinson are dead?
because they are idiots that dont have a life and nothing to do with there spare time.

I am guessing that someone said it as a joke, another person took them seriously, and then it spread to all of the other Twilight fans.
Now the gullible kids are clogging up here with their silly questions as well as other internet pages and forums.
