and of course who could forget :
Harvey Pincher
Played by: David Walliams
Catchphrase: "I want bitty!", "Bitty!"
Harvey Pincher is an upper-class mummy's boy who insists on "bitty", breast milk from his mother (played by Geraldine James) even though he is 25 years old, much to the dismay of his prospective wife and her parents. The sketches follow his engagement to Jane, through to their wedding day. The word "bitty" comes from combining the words "breast" and "titty".
