Baseball

Since the beginnings of baseball in the 19th century, players have adopted unwritten rules about how to behave during the game. According to sportswriter Ross Bernstein, these rules have evolved over time. Joe Garagiola wrote a book about baseball published in 1960, titled Baseball is a Funny Game, in which he mentioned the unwritten rules of baseball.

"Baseball is a game played with bat and ball and governed by rules set forth by a committee under the direction of the commissioner of baseball. Baseball is a game played by human beings and governed by unwritten laws of survival and self-preservation.
— Joe Garagiola"
