There is nothing more annoying than being rudely interrupted by a cell phone ringing in the middle of a movie, speech, or sermon. In Naples Italy, Father Michele Madonna used to put up signs asking people to silence their phones during services. At first, the signs worked, but over time, people would just answer their phones; cupping their hands over the receiver to reduce the noise. In response, Father Madonna took the drastic step of purchasing a jamming device and installed it after local authorities granted him permission.—Jim L. Wilson and Jim Sandell
