Sir Arthur Streeb-Greebling is a fictional character played by British comedian Peter Cook throughout his career.
Streeb-Greebling (or Greeb-Streebling, depending on Cook's mood) is a stereotype of the upper class English duffer, described as "narrow-minded" and occasionally a "heartless bastard".
Sir Arthur is the son of Lady Beryl Streeb-Greebling—a "wonderful dancer" who was still dancing at 107 years of age, and who "was capable of breaking a swan's wing with a blow of her nose"—who inspired him to take up his life's work of teaching ravens to fly underwater.
We're knee deep in feathers off that part of the coast ... not a single success in the whole forty years of training."
Sir Arthur's father claimed to have found the world's longest worm, at approximately three thousand miles.
As a result, Streeb-Greebling spent a great deal of his life trying to encourage worms to speak to him, again to no avail.
