Two small twin boys in New York spent the night using mattresses as ladders to climb in and out of their cribs with great facility. Once out, they built pillow forts, lolled around on the couch, and took time for gymnastics, including somersaults. It appears to have gone on throughout the night, even after the father came in twice to put them back to sleep.
These boys are twins in every way and their closeness is sweet to watch.
This time lapsed video shows what has to be an entire night of frolicking. It has had over 53 million shares and is funny to watch.
