Holidays of Future Passed

After dinner on Thanksgiving, Marge initiates taking the annual Christmas card family photo and, when Bart and Lisa complain about it, she notes that they will grow to appreciate the photos when they become older and have children of their own. Lisa questions why Marge would assume they will even have children in the first place, while Bart confidently claims that he won't, desiring for the Simpson family's legacy of dysfunction to cease. The episode jumps thirty years into the future (2041) via a compilation of Simpson Christmas cards accompanied by the song "Sleigh Ride" performed by The Ronettes. The photos finally settle on a future where Bart is a deadbeat, divorced father with two sons whom he does not see often; Lisa is a successful businesswoman who is married to Milhouse and has a rebellious daughter named Zia; and Maggie is the lead singer of a famous band and in the late stages of pregnancy. In his apartment at the former Springfield Elementary, Bart is visited by his sons, who inform him that their mother, Jenda, teleported them to his place because she wants him to act like a proper father by having him spend time with them. However, he plans on dropping them off at his parents' house instead, which his boys can hear. Meanwhile, Lisa fears that Zia is spending too much of her time going into the "Ultranet", a digital world that people enter with their consciousness by plugging themselves into a laptop through a cord in their belly button.
