My personal thoughts when watching the episode was that the Summer gag was a joke making reference to the short that inspired this series and a vocal number of fans who were outraged about Summer having a bigger "more annoying" role last season (their words, not mine, I like Summer as a character), but I also was worried how certain subset of fans could take it as how the episode was set up.
I don't think the joke has much of a problem by itself, just there's a problem the reason they say it feels a bit weighted, and it could be open to a few toxic interpretations and how some idiots might take it as it is open enough to be taken that way.
