Well, let's see about that... :-)

White from the starting position plays Nf3 and Nc3 and picking all black pieces
(except for the queen) with the knights. He also makes the moves Rh1-g1-h1 and
Ra1-b1-a1. When the black pieces are captured the both knights move back to b1
and g1. Now no castling rights are left in this position.
