Committing robbery to get back into prison

People really try their best to get out of jail; so meet this guy who desparately wanted to get back to jail. In an incident that would have astonished bystanders, a man walked into a bank, told the teller that he was robbing her and then told her that he was waiting for the police. He then waited for the police to arrive.
Turns out that this guy had been sentenced some years earlier, spent time in jail and then been released. After he came out, he never did appreciate the life he was leading and wanted to get back to the jail life.
