Want to start a drunken brawl at the next Pirate Festival?  Wear this t-shirt.   There are people better than I who can explain the origins behind pirates vs ninjas.  That's not the point.  The point is, this t-shirt will send those who know about it into peel of laughter, bets on who comes out of it without a bloody nose, and a great way to start a conversation.  Men's sizes.
