Beerdar is the latent homing ability exhibited by all males (and some females) that enables them to return to their place of dwelling whilst completely inebriated. (See Example 1 below). In cases of extreme inebriation, said ability may become repressed due to the large amount of alcohol in said person's body, often leading to them regaining conciousness in a randomn location. (See Example 2 below).

E=MC^3 is a popular spoof of Einstein's Theory of Relativity (E=MC^2). No one knows what would happen if E=MC^3 was actually the theory of relativity, but it would probably involve a very large explosion or some other sort of disastrous consequence (I'm betting explosion :P)
