There are some things kids will never understand: algebra, why they can’t stay up all night and, apparently, how to put cushions on a couch.

Watch the two kids in this video struggle to put couch cushions together. Yeah, it sounds easy, but these adorable boys manage to turn it into the kind of mind-bending challenge you'd see on 'Survivor.'

Eventually, they get it all pieced together. Forget algebra – it looks like geometry is going to be the subject that gives these little guys fits.
