This episode isn't too bad. I like the wordplay with the Arthurian names. Lessdred is Mordred.
Gyro invents his Sometime Tub, a machine that can take you not only to the past but a past that might have been. This invention would appear again in another episode.
It isn't King Arthur Gyro and the nephews meet, but King Artie, who likes to party. Gyro calls himself Sir Gyro de Gearloose and decides he loves living in this time period. Artie and his court are interested in Gyro's science, to the chagrin of Morloon, the court magician. Gyro would rather talk about jousting and chivalry. He continuously tries to perform as a knight, but he rediscovers that gadgets are his forte.
Funny when Morloon tries to make Gyro's magnet stick to the table, but I don't understand why Morloon has a German accent.
I like when Vacation Van Honk says that one of Gyro's gadgets, which is supposed to dress him for his vacations, instead dresses itself. He appears at Gyro's door wearing a barrel. Haha!
It's an okay episode, and Scrooge didn't even appear.
