Final Love of Chair skit
In the final “Chair” sequence, the sketch started normally. However, after performing a few actions the boy turned to face the camera and angrily interrupted the announcer who just said as always, "As our story begins, the boy is sitting" to declare "No, he isn't! The boy is quitting!" The background organ music suddenly stopped, and the camera changed to show a previously unseen door in a corner of the room. The boy quickly walked across the room and through the door, slamming it loudly behind him. After a moment's silence, the shocked announcer sputtered, "But...what about Naomi?" The scene then faded to black—and reopened on the entire cast of The Electric Company standing on a stage under a banner that read, "What about Naomi?" The cast sang a brief song that repeatedly asked "What about Naomi?" along with other questions about her ("Is she tall?" "Is she fat?"). The final lines of the song ran What about Naomi? What about Naomi? We shall never know.
