While Shawshank Redemption and Prison Break are highly rated movie and TV series respectively, a jailbreak is highly impossible in real life.
Tennessee is a state present in the south of the United States.
On Christmas, 6 inmates escaped Tennessee jail through the toilets. Yes, the toilets!!
The toilet seats were attached to the wall through bolts. Over time, no maintenance was done and the bolts became rusty. Thus, it became all too easy for them to escape.
Prior to this, there was a maintenance job done and there were some plumbing troubles which paved the way open for the inmates.
