My list:

Canterbury Tales (at least, the Prologue, the Miller's Tale and the Wife of Bath's Tale)
Shakespeare (as much and as often!)
Anything by Jane Austen
Bronte novels--Jane Eyre and/or Wuthering Heights
Dickens--maybe Bleak House or David Copperfield
Dracula (so much better than the movies)
Frankenstein (ditto)
Rhys' The Wide Sargasso Sea
short stories by Poe
Faulkner's As I Lay Dying (or anything else by him, really)
Toni Morrison--The Bluest Eye, Sula or Beloved
Twain's Huck Finn
Melville's Moby Dick
Hawthorne's The Scarlet Letter
Bradbury's Farenheit 451
Wharton's Ethan Frome
Miller's The Cruicible
The Iliad and The Odyssey
Antigone and/or Oedipus
Poetry--haven't listed any shorter poems but there's lots to choose from
and then, maybe, some contemporary stuff
