Bosko's Knight-Mare is a 1933 Looney Tunes short.
Bosko and Bruno are relaxing by the fire one evening. Bosko is reading a book about King Arthur's knights, when he suddenly falls asleep. He dreams of himself as a knight who sings and dances with the knights of the round table. An evil villainous knight abducts the fair maiden (Honey) and takes her to his castle. Bosko pursues, and while fighting the evil knight, Bosko wakes up to Bruno licking his face.
For a short time, Nickelodeon airings deleted some scenes of the Knights of the Round Table being movie star caricatures. This was done just to shorten the cartoon.
