When an economics class had Harris make an ad for a business, he and Klebold made a video called "Hitmen for Hire" on December 8, 1998, which was released in February 2004. It depicts them as part of the Trench Coat Mafia, a clique in the school who wore black trench coats, extorting money for protecting preps from bullies. They were apparently not a part of the Trench Coat Mafia, but were friends with some of its members. They wore black trench coats on the day of the massacre, and the video seemed a kind of dress rehearsal, showing them walking the halls of the school, and shooting bullies outside with fake guns.
