I was Tux!Ten at Kawa Kon this past year and entered the date auction. The girl who won me was obviously really excited, but since I'm the chair, I had to run and do some stuff before the dinner. When it came time to go to the dinner, I walked around the whole con looking for her so I could escort her. I saw her talking to her friends in one of the hallways, so I threw all caution to the wind.
I ran up right beside her, looked her up and down, said, "Hello, I'm the Doctor," glanced around us hurriedly, then took her wrist and said, "Basically, run." I took off down the hall with her in tow, and she was giggling like crazy the whole time.
On Sunday, I passed by in a different outfit and heard her talking to another friend. I caught just a bit of the conversation, something about how "he took my hand, and we ran all the way to the dinner, and then he ate like David Tennant."
