Two employees of a Domino's Pizza fanchise created a video at work purporting to show the prepartation of unsanitary food for customer delivery. Released onto the Internet, the video was seen by more than a million YouTube viewers. Customers were disgusted and the prank resulted in a public relations crisis for Domino's. The employees were fired and also arrested on felony charges for distribution of prohibited food.
