We was all glad as we could be, but Tom was the gladdest of all because he had a bullet in the calf of his leg.

– Mark Twain

The Adventures of Huckleberry Finn, Chapter 40. Huck on Tom, who loved adventure so much, the bullet was a memento. Jim won his freedom from slavery, Huck regained his friend, but Tom was ironically most happy because he had a battle wound to show off to everyone.
