If you're thinking about making a prison break, and digging a tunnel is your route out, you really need to make sure you've got up-to-date blueprints of the place.
Otherwise you could end up like this group of inmates in Argentina who, rather than shovelling their way to freedom, ended up breaking into the kennels for the jail's K-9 unit.
According to local media outlet Clarin, the group of criminals took around two days to make the tunnel at the Florencia Varela Penitentiary, Buenos Aires.
The escape to the tunnel measured just three feet wide and and five feet deep. To make sure their plans weren't uncovered by prison guards, they hid the hole under a slab of plywood and covered it with sawdust.
But sadly for the group of would-be escapists, it didn't make any difference in the end as they poked their heads out to find they had taken a wrong turn somewhere along the way.
And if things couldn't get any worse, their plan was well and truly scuppered when guards discovered their tunnel during a routine inspection of the prison on Monday.
