The mid to late 2000s saw an exponential gain in popularity for zombie walks, due largely to the success of zombie films at the time, such as the Resident Evil movies, 28 Days Later, Zack Snyder's Dawn of the Dead, Shaun of the Dead, George A. Romero's Land of the Dead, and Zombieland.
A: If a toenail has completely fallen off, it can take up to 18 months for it to grow back. A toenail can take longer to grow back if the nail bed has permanent damage. In some cases, old nails do not completely fall off, and they act as a protective barrier to the nail bed until the new nail begins to grow.
Unless your toe is in fact broken, a stubbed toe should usually completely resolve in a matter of a couple of hours. Occasionally a worse stub may take 24-48 hours. If pain persists after this, then the toe may be broken or there may be blood under the nail causing pain (seen as a dark patch or bruise under the nail).
