Donald visits the Museum of Modern Marvels, which showcases futuristic electronic appliances and inventions. He drops a coin on a string in the admission box and yanks it out. Once inside, he meets the Robot Butler, a brass
cyclops. The Robot Butler is programmed to greet guests and take their hats, but it has a flaw where it takes their hats whether they want to or not. It takes Donald's hat over Donald’s protest, but Donald does a magic trick to produce a
top hat. He encounters a robot hitchhiker exhibit that thumbs a ride when he imitates a passing ambulance. It pokes him in the eyes for tricking it into activating. The Robot Butler appears and takes his top hat, but Donald does another magic trick to produce a
bicorne. He finds a bundle wrapping machine. He ignores a sign that says not to touch it and pulls a lever, causing it to confuse him with a package and grab him and wrap him with cellophane and a red ribbon. After he frees himself, the Robot Butler appears and takes his bicorne. He does another magic trick to produce a
kepi and taunts the Robot Butler, who chases him after seeing his new hat. He hides inside a robotic baby carriage and swaps his kepi with a bonnet, playing along and acting like a baby. The carriage coddles him and offers a milk bottle, which squirts milk at his face. As he tries to escape, he's pulled back in by a mechanical clamp with the intent of keeping him safe. The carriage then thrashes him with a puppet toy, squirts more milk on his face, and puts a diaper on him. When he finally gets free, the Robot Butler appears and takes his bonnet. After he does another magic trick to produce a
bowler hat, he finds a robotic barber chair that he activates by using his coin. The Barber chair accidentally tosses him upside-down and straps him down and restrains him, then trims his rear end's feathers whilst giving his head a shoe-polish and shoe-shining. After he is released, he puts his bowler hat on his well-polished head. However, the Robot Butler appears and takes his bowler hat. Fed up with the Robot Butler taking his hats, he throws an explosive tantrum. ==Production==
