From an interview with William Eggleston:

Q: You never got your ass kicked for taking a picture?

A: Occasionally I will. But usually what I'll say is [in a really upbeat,
ingenuous voice] 'May I take your picture? I'm from Memphis!' ... I just
stumbled on it. You can use it yourself ... You could use some other city, but I don't think it would have the same ring to it. Say, 'I'm from Savannah.' I don't think that would work.
