Notable Numbers - Random Trivia Questions

Other than when writing checks and playing word games, we seldom spell out numbers since the numerical forms are so much shorter. But today you need to think about the letters. Using the standard U.S. spellings of the positive integers, how many of these do you know, and how many can you figure out?
