I'm blogging this story (from Roger Ebert's latest column) only because it makes me laugh helplessly, and because it's a rare example of a more-or-less perfect anecdote:

Q. I just finished reading your review of "Kung Fu Hustle" and I have to know, what is Jack Lemmon's story about seeing Klaus Kinski buying a hatchet at Ace Hardware?

A. Jack Lemmon told me that he was in line at Ace Hardware in Beverly Hills, and the sales clerk kept looking past him. "I may not be the biggest star in the world" he said, "but, jeez, usually when I stand in line, the clerk will notice me. I turned around, and there was Klaus Kinski with an ax."
