Modern Inventions pokes fun at modern conveniences. The scene of Donald in the barber's chair was submitted by Carl Barks as his first story contribution at Disney.[5] It is also the final Disney short to be released by United Artists.
Plot
Donald visits the "Museum of Modern Marvels" which showcases various futuristic electronic appliances and inventions. He uses a quarter on a line to get in (this allows him to keep his money and get in as well). Once inside, he is confronted with the "Robot Butler", a robotic golden cyclops. In a recurring gag, after Donald's hat is taken away from him by the Robot Butler (saying "Your hat, sir", every time this happens), Donald uses a magic trick to produce another hat. He says, "So!" and continues on his way. He first encounters a robotic hitchhiker, which activates when he makes driving noises, but when he laughs at it, it pokes him in the eyes. Next he goes to a bundle wrapper, with a warning sign which says "Hands off! Do not touch!" but Donald kicks the sign away and hops on. When he pulls a lever, the machine proceeds to grab him in two robotic arms, put transparent wrapping paper around him, and put him in ribbons, like a package. He manages to break out by vigorously shaking, and continues exploring.
All the time, Donald has been losing hat after hat to the Robot Butler, making Donald angrier and angrier. Eventually, the Butler chases him through the museum to an automated baby carriage, which Donald hides inside. Donald changes his current hat to a baby bonnet to wear as he is rocked as the song "Rock-a-bye Baby" is played. Donald starts crying about not getting his milk. The machine gets out a bottle of milk, but it hits him in the face instead of going into his mouth, making Donald agitated.
The Robot Butler is again attracted by Donald's laughing and yanks the baby bonnet off his head. Donald produces one last hat and goes to one exhibit he has not yet seen: a self-operating barber chair. Using his "cheat" coin, Donald pays to get the works, but the machine ends up flipping him over; the result is that the machine cuts off his tail feathers, cleans his bill, and coats his face with shoe polish. The Robot Butler appears yet again, and he then removes Donald's last hat, which causes Donald to eventually throw an explosive tantrum.
