I know this isn't a recipe, but I had to share my dad's GREATEST idea ever for cutting out watermelon. He just used a metal (bendable) ruler and scraped the whole water melon out in like two pieces! It was amazing! Darin had to bring a side dish for a pirate themed potluck, so this is what he took!
For the pirate ship part I just took pieces of paper and put them onto BBQ squewars and topped it with a skull and cross bones flag.
