Jonathan Balkin and his wife were wondering what their twin boys did after they went to bed. Well, thanks to a surveillance camera, they got their answer. Andrew and Ryan proceeded to climb out of their cribs and had a grand ole time running around the room, creating a stack of pillows and taking short breaks on the couch to catch their breath.

The adorable toddlers FINALLY exhausted themselves and climb back into their cribs for a few hours sleep.

Their antics took so long, Jonathan had to speed up the video to get it into this shorter clip...
