How to Pick a Watermelon

We have a local farm 5 minutes from our house. Last summer I was choosing a watermelon there and they told me that you want to look for bee stings.
See picture below..

like this. The more the better. You see, bee's can tell which ones are the sweetest. So they put their little stingers in the watermelon making the imperfection in the rind. I used to stay away from those watermelons, but you see they are the best ones. Choose a bee stung watermelon for the sweetest taste.
