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.
