I've found a website with many funny quotes about 1929 crash:
"[1930 will be] a splendid employment year."
- U.S. Dept. of Labor, New Year's Forecast, December 1929
"Hysteria has now disappeared from Wall Street."
- The Times of London, November 2, 1929
"We will not have any more crashes in our time."
- John Maynard Keynes in 1927
