One Piece/NCIS crossover: Can you imagine the chaos from such a thing? Where either the One Piece crew gets sucked in to the NCIS world or the NCIS crew gets sucked into the One Piece world. If it is the latter, then let it start pre-One Piece like right after the Sabo incident. You know so that they can get used to the One Piece world. Oh, both Ziva and Kate must be part of this, too.
