[Rick and Morty] So why exactly did Mr Meeseeks get pissed at Jerry? (more detailed question inside)

Did they get pissed at Jerry because it was taking so long to accomplish a task that should of taken a short time? Would they have the same problem if I asked them to remove an entire mountain by hand? Something that would take them hundreds if not thousands of years. But that is the expected normal time frame. Or would they in a matter of a few days in go bonkers?

A simple way to ask my question is what makes them go nuts the same time frame every time or a time frame relevant to the task. Or was it because the task was starting to look like it was incompleteable?

Because it's a sissyphean task. When you move move a mountain by hand, you can actually see the results of your labor, even if it's going slowly. But with Jerry it's one step forward and two steps back. You see him start actually improving and taking some advice, but it doesn't go exactly how he wanted it and gets frustrated. He decides the working that you gave didn't do anything and goes right back to ignoring you.

They only reason Beth was able to get through is because while Meeseeks are submissive, she's very dominating and controlling which is what Jerry needs. Like Rick said, they're not gods. There are tasks they can't complete.
