I believe you're looking for page 211 of Hyperbolic Structures on 3-Manifolds I: Deformation of Acylindrical Manifolds (Annals of Math., 1986), which includes the following paragraph:

>A complete description of the three spaces $AH(M)$, $GH(M)$, and $QH(M)$ is
 certainly not rigorously known, but here is a conjectural image, of which certain
 features can be rigorously proved. Let us stick to the case that $M$ is a compact, acylindrical manifold. Then $H(M)$ is a hard-boiled egg. The egg complete with
 shell is $AH(M)$; it appears to be homeomorphic to a closed unit ball. $GH(M)$ is
 obtained by thoroughly cracking the egg shell on a convenient hard surface.
 Apparently no material is physically separated from the egg, but many cracks are
 developed - cracks are dense in the boundary - and at the same time, the
 material of the egg just inside the shell is weakened, so that neighborhood
 systems of points on the boundary become thinner. Finally, $QH(M)$ has uncountably many components, which are obtained by peeling off the shell and
 scattering the pieces all over. Each component is homeomorphic to some
 Teichmuller space - it is parametrized by Euclidean space of some even dimension.
