P worked in a factory handling yarn. At the end of the shift, employees assisted each other with removing lint from each other's clothes by using an air hose. A fellow worker placed the air hose in the vicinity of P's rectum and caused his rectum to be perforated. The worker’s compensation commission denied recovery as this accident occurred from horseplay. P appealed and argues that an employee who is injured as a result of 'horseplay' is entitled to compensation where the injury arose out of and in the course of his employment. D contends that injuries resulting from 'horseplay' are not compensable.
