"Something that started decades ago and was applauded and inoffensive is now politically incorrect. What can you do?," says Lisa. The show then panned to a picture of Apu.
Shortly after the episode aired, social media went into overdrive, with many saying it was a weak response to the serious accusations of racism and a 'slap in the face'.
In particular, one person who wasn't pleased was comedian Hari Kondabolu.
Kondabolu was one of the first people to properly raise the issue in his documentary The Promblem with Apu in which he used Apu and the racially stereotypical treatment of him by the show as a springboard to explore broader problems of representation in the entertainment industry.
Jean's tweet is the first time the showrunner has properly engaged with the criticism, having flippantly tweeted out things such as, "Can't wait to see what's on my twitter account today!" following the episode airing.
Until now, he had refused to respond to the criticism, saying instead that the producers would prefer the episode "speak for itself".
We'll have to wait to see what Jean considers to be a "right" way to respond, but it'll no doubt prompt further discussion.
