Oh how I love the radish too. I use to drive a truck and haul produce out of Florida many years ago. One of my fav pickups was this little radish farm where they would always gave me a bag of the fresh ones. One day while watching his little operation I noticed that some radish would float and others sank in the water. I asked the guy what was the difference thinking to myself this might be secret way of telling which was hot and which was sweet. NOPE guy just looked at me and asked if there was reason why some turds float and some sink!
