Modern Inventions

Modern Inventions is a Donald Duck cartoon. Released on May 29, 1937, and directed by Jack King.

The plot
Donald visits "The Museum of Modern Marvels", which showcases various futuristic electronic appliances and inventions. In the museum, Donald encounters and struggles with many strange and whimsical machines, all of which seem to be against him. A running gag throughout the picture has the Robot Butler appearing to take away Donald's hat, with the words "Your Hat, Sir." After encountering a robotic hitch-hiker, a wrapping machine and a fully-automated baby carriage, the short ends when Donald attempts to scam a robotic barber chair and winds up getting a haircut on his behind and a shoe-shined bill.
