OK, I remembered another one :-).
1995, I played Nancy in Oliver in a small town in Massachusetts. As those of you who do small town community theatre know, shows with kids can be really popular because they draw such a huge audience of family members. Therefore the director took just about every kid who auditioned - there must have been 30 little kids in the cast.
About 10 years later I had moved away and met some old work friends for dinner at a restaurant in another small town in Massachusetts, a good couple hours away from the first town. The young waitress (late teens, early 20s) comes to our table to take our order, gets to me, looks at me, and says, "Hey - weren't you Nancy in Oliver at Small Town Theatre Group?"
Turns out she had been one of Fagin's kids.
