All watermelons have an inedible outer shell. Given how tasty they can be during the hot summer months, many people have wished that a larger part of the watermelon could be eaten. Their complaints pale in comparison to what happened to this guy. The person who posted this photo on Twitter had literally bought the worst watermelon in the universe. It was brave of him to even attempt to post this thing on social media.
Buying a watermelon like this is the same thing as buying a Chinese-knockoff iPhone that charges to 103% and then bricks itself. Although to be honest, in comparison to the knockoff iPhone, this watermelon *shouldn't* explode, although that can't be confirmed at this point. Who knows what kind of weird genetics this watermelon carries?
