• State and federal authorities descended on Quality Pork Processors of Austin, Minn., in December after 11 workers contracted a mysterious neurological illness, which apparently came from inhaling the mist that results from blowing hogs' brains out with compressed air. • New York City apartment house doorman Jonah Seeman was suspended in December after excessive complaints about his bad breath. His job, said a resident, is opening the door, "not ... his mouth." • Maurice Fox, 77, said in December he would comply with the wishes of the Kirkham Street Sports and Social Club of Paignton, England, to sit only by the front door so he could excuse himself when he needed to pass gas, which management said had become a problem.
