This paper attempts to study the consistency of several basic game-theoretic axioms. Two by-products are the introduction of information-dependent games, and a formal treatment of the framework of game theoretic axioms. In this setup a version of the Surprise Test Paradox is used to prove that common sense cannot be common knowledge.
