The problem of grues is, of course, their recursive nature. To wit: A) Grues are found wherever it is very dark.
B) There are no light sources on the inside of a grue. Therefore, being eaten by a grue is a fate which entails being eaten by an infinite number of progressively smaller grues, presumably nested in a geometrically complicated and interesting way. The proper way to unify quantum mechanics with this theory, that of grueitvity, is to date unresolved, and an active field of research among professional zorkologists. Lolgrues | MetaFilter
