“Dates are hard to remember because they consist of figures; figures are monotonously unstriking in appearance, and they don't take hold, they form no pictures, and so they give the eye no chance to help. Pictures are the thing. Pictures can make dates stick.”

Samuel Clemens was an American writer of the late 19th and early 20th centuries. He is best known for his satirical novels *The Adventures of Huckleberry Finn* and *The Adventures of Tom Sawyer*, which blend humor with sharp social commentary. His wit and keen observations on human nature remain widely influential.
