If Alexander Graham Bell had not secured the patent for inventing the telephone, Elisha Gray would have gotten it because they both applied for the telephone patent on the same day (Feb 14, 1876).

Square or cube watermelons are watermelons grown into the shape of a cube. Cube watermelons are commonly sold in Japan, where they are essentially ornamental and are often very expensive, with prices as high as US$200.

I'm a product manager by trade and, until recently, never really been satisfied with the answers I've come up with. However, I've found one I really like.
I try to come up with two tweet length product ideas per day. I don't judge the ideas. They can be big or small. They just have to be plausible product pitches. I've been doing this for a couple of weeks now and it has been a small enough exercise that I can commit to doing it daily but big enough that I can feel myself stretching. Most importantly, I've noticed more, better ideas coming to me at other parts of the day.
