Plot
Bugs Bunny is reading a book about the Knights of the Round Table while having his ears washed, when an apple falls and hits him on the head and the washing equipment; it transports him back to the time of King Arthur. When he wakes up he encounters a knight named Sir O of Kay, Earl of Watercress, who challenges him to a joust. Bugs trips the knight's horse, sending him flying into a castle tower.Pursued by a fire-breathing dragon, Bugs defeats the creature with seltzer, causing it to cry and run away. Seeking refuge in another castle, Bugs encounters Merlin of Monroe, a supposed sorcerer. Merlin attempts to use "magic powder" to transform Bugs into a pig, but Bugs turns the tables on Merlin by transforming him into a horse. To return to the present, Bugs tosses an apple to hit himself on the head. Successfully returning to his own time, Bugs encounters a farmer with a plowhorse resembling Merlin's transformed state. Dismissing the resemblance, Bugs continues on, only to be surprised when the farmer addresses the horse as "Merlin".
