I was at Hong Kong
Disneyland, trying to get an autograph collection started. But looking at the princesses in front of the castle, I thought about how boring it must get having pictures taken with people who dont speak English and neither know nor care who you're supposed to be. So when my turn came to meet Snow White, I introduced myself and as innocently as I could, asked her "Do they call you Snow White because you have dandruff?"
She started to laugh for moment at the sheer unexpectedness of it, and then regained her composure and began to tell me the origin of her name (which I already knew, but decided not to say anything).
I didn't about it again for while. Then, on the next day (or the same one? I forget) I got my picture taken with Aurora. As she was signing my autograph book, she asked me for my name (so she could sign it to "Prince So-And-So"). When I told her, she told me without missing a beat "Oh, Snow White told me about you! Don't worry, she doesn't have dandruff!"
This totally caught me off guard. I'm completely sure that the friend of Snow White wasn't also a friend Sleeping Beauty in this instance.
I was almost too embarrassed at this point to face another princess that day, but the Disney nut in me just had to get Cindy's autograph. I told myself that there was no way something like that was going to happen again. Sure enough, after I had my picture taken, she asked me if my name was So-And-So. Embarrassed, I told her it was. She then proceeded to remind me that Snow White washes her hair very thoroughly.
If nothing else, that totally made my trip. It was so cool how after I had given someone a funny and unexpected moment, I got two back. Gotta love that Disney magic!
