The video shown above should be viewed as a public service announcement to all "Game of Thrones" fans looking for ways to use that sword they bought on the Internet. Do not use it to cut a watermelon. Especially if that watermelon is sitting on a glass table.
Seems like a stating-the-obvious type situation. Not for one man, who attempted to cut a whole watermelon with a sword, on a glass patio table, on top of a cutting board.
Because if you're going to cut a watermelon with a sword, it seems only logical to have a cutting board underneath it.
