10 Stories Behind Dr. Seuss Stories

3. If I Ran the Zoo, published in 1950, is the first recorded instance of the word “nerd.”

5. Green Eggs and Ham. Bennett Cerf, Dr. Seuss’ editor, bet him that he couldn’t write a book using 50 words or less. The Cat in the Hat was pretty simple, after all, and it used 225 words. Not one to back down from a challenge, Mr. Geisel started writing and came up with Green Eggs and Ham – which uses exactly 50 words. The 50 words, by the way, are: a, am, and, anywhere, are, be, boat, box, car, could, dark, do, eat, eggs, fox, goat, good, green, ham, here, house, I, if, in, let, like, may, me, mouse, not, on, or, rain, Sam, say, see, so, thank, that, the, them, there, they, train, tree, try, will, with, would, you.
