I'm really good at sniffing out plot twists and am rarely ever surprised. In fact I think the only plot twist to surprise me is the one at the end of the Harry Potter series, you know the one about Snape.
EDIT: Actually I remembered that there were a few plot twists in One Piece that surprised me. Brook's past, the whole thing with Ace, and Hody's motivation were big ones.
