Considering the horrors of Hoarders, YABU to doubt these are real, as sad as that is.
If I needed to stage a messy room for a contest, I could easily dump drawers of clothes and piles of towels on the floor. With kids, it's easy enough to throw toys around, too.
But some of those photos show what looks like an accumulation of days (if not weeks) of food wrappers, not to mention actual filth (crumbs, etc. scattered all over the place). Who would normally have those on hand? Who would willingly make such a mess just to enter a contest to win a bed, knowing that you then have to clean it up yourself?
