This creative and rather humorous Think Outside the Box Tic-Tac-Toe shirt reminds us to not confine ourselves to the boundaries and limitations of everyday thought. Where did the phrase come from? A number of people claim to have created the phrase, which was widely used by business consultants and management coaches in the late 1960s and early 1970s. The “box” that the phrase refers to is related to the nine dots that make up the topographical puzzle called the nine dots puzzle. To complete the puzzle, one must draw four straight, continuous lines that pass through all nine dots and it must be done without ever raising one’s pencil off the paper. The key is to not stay within the square formed by the nine dots. This Think Outside the Box shirt applies this notion to the popular pencil and paper game Tic-Tac-Toe.
