Homer watches a TV commercial for the Seat-to-Feet Lift Chair and then sees the price displayed as $1,100.

2. The Australian boy band Doe-Eyed Boys takes the stage and performs their opening song at a concert attended by Homer and Lisa.
Band: When we harmonize / And you look in our eyes / You’ll see it’s no surprise / That we’re your Nobel Prize.

Having recently learned of Amelia Vanderbuckle, Springfield’s original female inventor and the first female graduate of Springfield Tech, Lisa unveils the inventor’s greatest invention which had not seen the light of day while she was alive, decades ago.

Barney: A loom?!
Superintendent Chalmers: That isn’t science, that’s home economics. Everyone, storm the stage!
Lisa: Not so fast! This is no ordinary loom!
Barney: Even an extraordinary loom is the most boring thing I can think of.
Lisa: This is much, much more than just a loom.
[She inserts a board with cutouts and then cranks a wheel. The loom begins operating and weaves the message HELLO WORLD.]
Carl: It’s alive!
Barney: And polite!
[The loom weaves the message ENTER OPERAND.]
Lisa: “Operand”? Looks like it wants us to give it a math problem.
[In order, she enters boards labeled 27, x, and 35, and then cranks the wheel. The loom weaves the message 945.]
Professor Frink: Oh, my God. Oh, God! It’s the first computational device! People, people, don’t you see? The board acts like punch cards and the loom like a computer, with the Charles Babbage and the John von Neumann . . . Let’s have “the square root of nine” cheers for Lisa!
[The loom weaves the message THE SQUARE ROOT OF 9 IS 3.]
Crowd: Lisa! Lisa! Lisa!
Lisa and a group of coders work in the family’s living room to create an app. Some boards and papers posted on the walls contain mathematical symbols.
