One of the "Life in Hell" books did a gag on this. Jeff and Ackbar's Cryogenics Hut, or something like that. One of the panels showed technicians gathered around a dog with Binky the rabbit's head sewn on it. "Welcome to the future! You owe us one million dollars."

As I recall, extropian / cryogenic dogma has given up on actual ressurection of the frozen corpse. They're assuming cloned bodies with brains recreated by nanotech disassembly of the frozen brains.
