The final sketch showed Mick Jagger as the teacher of a small group of graduating high school seniors. He commends a student who has decided to become a nun, and Bobby Moynihan stands up. Then, Jagger wants to say farewell to a student "who has been with us for seven years" - he jokes that that's a long time for a student. Jagger joins the band to start singing "Ruby Tuesday," and Kristen Wiig gets up, as the other "students" join the band singing. It becomes clear that this was Kristen's last night on SNL. The whole cast, including surprise guests Jon Hamm and Steve Martin, sing along, dance with Kristen, and wish her farewell.
