Back in June, the prison escape that took place at the Clinton Correctional Facility made headlines worldwide. People just couldn't understand how David Sweat and Richard Matt escaped. Want to see video of how it was all done?

CNN's Randi Kaye shows the world how one of the most famous prison escapes of the 21st century took place.

As we all know, the prisoners escaped by cutting through the walls in their cells, scaled a cat walk and escaped through a manhole cover a block away. According to Syracuse.com, there was also more to it.

A series of tunnels led from the prison to the manhole, allowing the inmates to follow heating pipes and the prison's inner workings to escape. Investigators spent about 20 minutes to complete the route"

Still by far, one of the craziest things of the 21st century, and definitely of 2015.
