Mary Poppins relates the founding of the United States with a run on a bank:
Mr. Dawes: In 1773, an official of this bank, unwisely loaned a large sum of money, to finance a shipment of tea to the American colonies. Do you know what happened?
Mr. Banks: Yes, sir. Yes, I think I do. Uh, uh, as the ship lay in Boston harbor, uh, a party of the colonists dressed as Red Indians, uh, boarded the vessel, behaved very rudely, and, and threw all the tea overboard. This made the tea unsuitable for drinking, even for Americans.
Mr. Dawes: Precisely. The loan was defaulted. Panic ensued within these walls. There was a run on the bank!
Mr. Dawes (Snr): From that time to this, sir, there has not been a run on this bank until today! A run, sir, caused by the disgraceful conduct of your son. Do you deny it?
It then goes on to equate humanity's emancipation from capitalism to the liberation of words we utter, the languages we speak:
Mr. Banks: Supercalifragilisticexpialidocious. Mary Poppins was right. It's extraordinary. It does make you feel better!
Mr. Dawes (Snr): What are you talking about, man? There's no such word.
Mr. Banks: Oh, yes. It is a word. A perfectly good word, actually. Do you know what there's no such thing as? It turns out, with due respect, when all is said and done, that there's no such thing as you!
