Probably the best Lupin the 3rd's movie ever, the Castle of Cagliostro offers a lot of action in the smallest and unknown state of Cagliostro, "the smallest state in the world". I don't know where this state is, but it's probably somewhere around Italy, if we look at the huge spaghetti with meatballs tray that Lupin and Jigen get in a tavern.
After a quick conversation with the waitress about rings, princesses and so on, they start with an original spaghetti fight with fork and spoon.
There are no written rules for spaghetti fight, and no instructions left from Our Saucy Lord. They fight it with a fork and a spoon, so that would surely be different from an hypothetical Italian version of the game, which would be played only with a fork.
But at the end the winner in both cases would be Jigen: thanks to a quick rotation of his tools , he creates a huge spaghetti ball, making it bouncing from the tray to his dish. Well played, Jigen, the holy match is yours.
