Interesting fact:

Brash, outspoken, colorful Dallas Mavericks' owner Mark Cuban once publicly quipped that the manager of officials of the NBA “wouldn’t be able to manage a Dairy Queen.” The ice cream chain and its many employees took offence to the statement and invited him to manage a Dairy Queen shop for a day. Cuban accepted the company’s invitation and put in a full day’s shift at a Dairy Queen. In the end it resulted as a huge PR victory for all parties involved.
