Ida drops by Brenda and Rhoda's apartment on the strong possibility that Joe will be there - based on intel from a reluctant Brenda - Joe who Ida has not yet met. Rhoda, who isn't quite ready for Joe to meet her parents, thwarts Ida's plan of attack as she and Joe are meeting elsewhere for their date. Rhoda later learns the true extent to which Ida will go to meet Joe. When Rhoda and Joe discuss the issue, Joe suggests they make a day out of each meeting the other's parents, they having lunch with Joe's parents, and having dinner with Rhoda's parents that same day. Rhoda agrees, but she urges Ida not to make a fuss. Although nervous about meeting Joe's parents, it's something that they tell her about their own relationship that surprises her. Rhoda is equally as surprised by the Ida who shows up to dinner.
