I fetched this autograph personally at the FedCon 23.
Bai Ling is the first person who ever called me "Sir". She was at the FedCon because of her role in "Star Wars" (which was sadly cut out) and therefore a bit surprised I gave her a "Sky Captain" picture to sign. We talked a bit about the movie, my picture and before she signed it, she made a photo of it (so I guess she really liked it).
