That wasn't it. Anyway, it was a very short funny thing, really short, and I couldn't find it. I had read it in a library book, a collection of short stories, and I wasn't really even sure of the name of that book. I remember that it was one of those "best of" books, and that it was in the same volume with a story called "The Ugly Chickens." (The Ugly Chickens is also a very funny story, though not nearly as short as the one about tomatoes.) Since I did not want to go back to that library and try to find a collection of short stories containing the story "The Ugly Chickens" in order to find another story about tomatoes, I have many times tried to find the tomato story on the Internet.
A few days after that, I forgot about the whole tomato thing, and we went to Chipotle's. But they still had pico de gallo, so my burrito was not ruined.
