Hip to be Square

An 84-year-old farmer had the idea of growing square shaped watermelons to help solve the problem of "lack of space" when placing the original round variety in Japanese refrigerators. "A fat, round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves."
30 years later, Japanese farmers are still inserting the melons into square, tempered glass cases while the fruit is growing on the vine and are selling this square variety in Japan and now the UK.....will the US have them next?
