Do you watch Rick & Morty? If you do, you must be familiar with Mr Meeseeks, the blue aliens who can be ushered into existence to enthusiastically perform a single task.
The thing with a Mr Meeseeks (despite the name, Mr Meeseeks is a species rather than an individual) is that it is designed to perish the moment it has completed its task. It's not engineered to live for any significant length of time, and that becomes quite the problem when Jerry, Morty's dad, tasks a Mr Meeseeks with taking two strokes off his golf game.
