  Entanglement and nonlocality are studied in the framework of
pre-/post-selected ensembles with the aid of weak measurements and the
Two-State-Vector Formalism. In addition to the EPR-Bohm experiment, we revisit
the Hardy and Cheshire Cat experiments, whose pre- or post-selected states give
rise to curious phenomena. We then turn to even more peculiar phenomenon
suggesting "emerging correlations" between independent pre- and post-selected
ensembles of particles. This can be viewed as a quantum violation of the
classical "pigeonhole principle".
