In the Rick and Morty episode "Meeseeks and Destroy", Rick gives the family a Meeseeks box to help them out. This box creates a being called Mr Meeseeks, whose only goal is to fulfill any request made of it before dying.
Jerry's request is to take 2 strokes off his golf game, which proves difficult for Mr Meeseeks and results in his intial Mr Meeseeks requesting help from an additional Mr Meeseeks. When that fails, the additional Mr Meeseeks also calls for help from a third Mr Meeseeks, the cycle continuing until there are dozens, if not more, Mr Meeseeks.
One of the Mr Meeseeks says that Mr Meeseeks' aren't meant to live as long as they are now, and that things are getting weird.
Out of desperation, the end up attempting to kill Jerry, thereby taking all the strokes off his game and fulfilling their request. Jerry has to prove his golf skills under pressure in order to survive.
But why do the Mr Meeseeks not simply kill themselves, if death is their end goal anyway?
