[Rick and Morty: Morty's Mind Blowers] How often do Scenarios Three and Four occur and how much does Summer get paid to deal with them?
gpt
Often enough that Summer has seen it before, but not often enough that she doesn't need the instructions to know what to do. Given Summer's reaction to Rick and Morty when they wake up, I'd say it skews towards the high end. 

To estimate where exactly that high end is, count the vials. Rick is kind of a moron overall, he's probably never thought *not* to take Morty into the room of memories. Scenario 3 seems to involve Morty losing his mind but Rick not, since Summer asks Rick if it is a Scenario 3, then ignores him when she finds out it's a scenario 4. 

Presumably Morty behaves the same way every time he goes into the room. Which means that every time Rick needs to modify Morty's memory, they do the exact same song and dance.
