One of the things I love most is being able to interact with characters!!!
The most memorable, however, is um.. perhaps a bit, well, let's just call it suggestive in nature..
My best friend from college and I were having breakfast at 1900 Park Fare, or rather waiting to be seated. While we waited, we noticed that outside the holding cell, um, waiting area, there was a topiary of Mary Poppins. Being girls in our mid 20's we started joking about Mary Poppins' bush. We were quiet and amusing ourselves to pass the time. Then Mary Poppins herself came out to meet everyone. We laughed a little harder. As she got around to us she inquired as to what was so funny, asking if we were being good girls, and well, it must have been that slightly devilish sparkle in her eye, we told her that we were talking about her bush. And without missing a beat she said, "oh yes, my bush, it needs a lot of maintenance, must be trimmed all the time!!"

She knew exactly everything we were discussing, played along, and even offered to go outside (Big no-no apparently) and pose, all three of us, in front of her bush. The BFF and I still can't talk or reference MP without laughing hysterically.
bummer.. I'd post a pic, but I'm still too new!
