The most elaborate [prank I knew of] involved 40 of the 48 residents of West Norris Hall. A variety of chains, padlocks, and other devices were developed for the project. At five minutes before midnight, 40 men moved with synchronized watches to all the doors of the (then) Women’s Quadrangle as well as Burling Library. All the doors were locked.
Those inside made various choices. One young man, under the alcohol weather, feared being found in the women’s loggia after hours. He feared so much that he leapt through a window, demolishing a bush in the process. Of course, some of the culprits were recognized.
The dean of men came to visit Norris Hall, and with what appeared to be mostly-hidden admiration, as well as more obvious disappointment, placed the entire hall on social probation for the semester.
