Police Car Hack
The car was constructed from the outer metal parts of a Chevy Cavalier attached to a multi-piece wooden frame, all carefully assembled on the roof over the course of one night. The Chevy been painted to look just like a Campus Police car from all sides, and a dummy dressed up as a police officer sat within with a toy disc gun and a box of donuts. The car, numbered "pi", also sported a pair of fuzzy dice, the license number "IHTFP," an MIT Campus Police parking ticket ("No permit for this location"), and a yellow diamond-shaped sign on the back window proclaiming, "I break for donuts."
CalTech Cannon Heist
Caltech's famous Fleming Cannon was transported to MIT by students posing as the Howe & Ser Moving Company. The cannon appeared in the middle of the night at the base of MIT's Green Building. A large brass rat (MIT class ring) made of gold-plated aluminum was placed on its barrel. In honor of its origin, the cannon was pointed towards Pasadena, CA. The cannon appeared during MIT's Campus Preview Weekend, which also was the 20th anniversary of the original heist of the cannon by students from Harvey Mudd College. The cannon was subsequently returned to CalTech.
MIT hacks are world-famous pranks that are a beloved part of MIT's culture. Not only must a hack be clever, elegant and amusing, hacks are expected to adhere to an informal, self-enforced "code of ethics" that has evolved over the years. According to the "hacker ethic," a hack must be safe; not damage anything; not damage anyone, either physically, mentally or emotionally; and be funny, at least to most of the people who experience it. Anything that directly contradicts this code likely will not be considered a "hack" by most of the MIT community.
