Watermelon, the perfect summer treat...only $4000?

A small, black watermelon from Japan recently sold for 300,000 yen, or about $4000. Apparently, " the fruit is lauded for its crispy texture and extra sweet juice".  Link is here.  The price is an absolute bargain compared to a 2007 watermelon which sold for 650,000 yen ($8100).

 

For my money, I'd prefer a Japanese square watermelon.
