although i dont really have an opinion other than its funny, i see what you are saying Buzzy!
with that being said, it makes sense that some of then 'could' be staged and some 'could' be accidents.
you wont get to much traffic on a few accidents, it just gets brushed off as a once in a while thing.
when you add a few staged ones it creates a collage and a collage will create conversation.
then comes blooper videos, crazy hits on online videos, then high publicity for better sales!
