Andre and Ryan Balkin were filmed causing havoc in their bedroom by climbing out of their cots, pulling all the cushions onto the floor and jumping up and down on them.
But as soon as the door is closed again, out they get.
The twins then decide to re-create their pillow mountain at the other side of the room.
They jump on the sofa, in and out of their cots, and run up and down the room.
This time, both mum and dad come in to try and diffuse the party by tidying everything back up and putting them to bed again.
But does that stop them? Of course not.
The video, posted on Fox 13 News Facebook page on 18 March, had 63 million views in just three days.
Sleep? Who needs sleep these days...
