Knowledge 1: My Fair Lady (film)
Eliza's father, Alfred P. Doolittle (Stanley Holloway), a dustman, shows up three days later, ostensibly to protect his daughter's virtue, but in reality simply to extract some money from Higgins, and is bought off with £5. Higgins is impressed by the man's honesty, his natural gift for language, and especially his brazen lack of morals. Higgins recommends Alfred to a wealthy American who is interested in morality. Eliza goes through many forms of speech training, such as speaking with marbles in her mouth, enduring Higgins' harsh approach to teaching and his treatment of her personally. She makes little progress, but just as she, Higgins, and Pickering are about to give up, Eliza finally ``gets it ''; she instantly begins to speak with an impeccable upper class accent.
