I think all the short stories in Ray Bradbury's collection "The Illustrated Man" have twists. Strong recommend, if you've never read it.

Hmmm. Many of Kurt Vonnegut's stories have astonishing twists, but I can't think of any that are short (although I guess most of the early ones were initially magazine serials).
