INJOFor three months, Jonathan and Susan Balkin could hear their two-year-old twin boys moving around in the middle of the night.

They tried everything to keep their kids in their cribs, reports NBC 4, from changing out the beds to bolting things to the walls. Finally, they decided to install a camera to keep a close eye on Andrew and Ryan.

Then on March 13, Jonathan and Susan finally figured out what their kids were up to in the middle of the night. (Hint: They weren't sleeping.)

The parents posted a time-lapse of their findings on Facebook where it has since been viewed 11 million times — and for a good reason.

It's hilarious.
