In what may sound like an attempt to escape prison guards, much like Solid Snake out of the Medal Gear Solid franchise, a 42 year old Turkish man escaped a German prison using nothing but a cardboard box.
The Turkish man agreed to work in a small shop in the prison, at would leave boxes of supplies for a courier to pick up once a week. Well, one day the inmate decided to crawl into one of the cardboard boxes and as usual, the courier picked up the boxes and placed them in the back of his truck.
When the man made it past the prison gates he tore a hole in the tarpaulin that was placed over the boxes! The driver of the truck alerted police whenever he noticed the tarpaulin was flapping in the breeze. The escaped convict presumably had an accomplice outside of the prison, ready to pick him up and drive away!
