Anecdotal Evidence: Brushes with Fame: Correspondence

I sent Jamie Zawinski some mail about randomly-generated textual nonsense. He replied politely.
I wrote a letter to Dave Barry clearing up some of his uncertainties in his book Dave Barry Does Japan. I told him which of the Japanese rock bands he'd observed was "King Fucker Chicken." (It was the one with the male lead singer wearing a plaid skirt.) I bet he was really glad to learn that. He sent back a nice thank-you card.
I sent Dishwasher Pete a quote about dishwashers from a book I was reading. He sent back a postcard saying that he remembered growing up in the San Francisco neighborhood where I was living, and had probably delivered newspapers to my apartment building.
Some friends gave me a packet of Brazilian chocolate candy cigarettes. I forwarded them to Cardhouse which led to a discovery.
