There is probably a posting somewhere on a Miata Forum, and the story goes like this:
"Well, I went to Starbucks this morning on my way into the office. When I came out with my skim, no foam, extra hot, grande latte, there was this dude trying to steal my car. During the struggle, I whacked him with his own cell phone. As I was driving away, I looked in my rear-view mirror and saw him successfully steal a Porsche! I am kind of shocked he didn't go for that car first!!"
