One Last Job

"(narrating) "This was my last job. Every job was 'my last job'.""

- Griffith, The Detonator

A seasoned criminal announces that he'll take on One Last Job before retirement to peaceful honest life. Usually, this leads to either death by Retirony due to either a Plethora of Mistakes or his superiors demonstrating Resignations Not Accepted, or a Ten-Minute Retirement.

Compare That One Case for people on the opposite side of the law.
