The Three Musketeers

The Three Musketeers was a novel written by Alexandre Dumas. When infected with an unknown disease on Stardate 1704.2, Lieutenant Sulu began chasing crewmembers with a foil and calling them Richelieu, the antagonist of the book. After Sulu had been subdued, Lieutenant Commander Spock told the security crewmen to "take D'Artagnon here to sickbay," a reference to one of the eponymous Musketeers.
