On Sunday night, Supreme Court Justice Ruth Bader Ginsburg sat down with NPR reporter Nina Totenberg and former President of the Supreme Court of Israel Dorit Beinisch for a conversation about law, being a woman on the high court and Tumblr. The event was held at 92nd St Y in New York City.

During the conversation, Ginsburg revealed that yes, she does know that the Internet is talking about her, and yes, she does own "a large supply" of 'Notorious RBG' t-shirts. (Fast-forward the video to 1:08:30).

She also discussed the opera based on her and Justice Antonin Scalia's friendship, which she says will hit the stage next summer. Her favorite scenes involves the time when her character drops on stage through a glass ceiling to rescue Scalia, who has been trapped in a locked room for excessive dissenting. She also loves Scalia's "rage aria." (Ginsburg's review of the opera and her friendship starts at 1:42:30.)

Ginsburg also said she gets asked a lot about when she thinks there will be enough women on the Supreme Court. Her response, always, is: "When there are nine."
