1987-88 was a bad season for the Los Angeles Kings. The perennial cellar dwellers had had another tough year, going 30-42-8. On one particular night against visiting Montreal, one fan decided to show his displeasure.
This fan somehow snuck a live chicken into the building. He dressed the chicken in a customized purple Kings uniform and tossed the poor critter onto the ice. The startled chicken slipped all over the ice before someone finally captured it.
