Mark Cuban is the funniest and one of the most engaged owners in the NBA.  After the Dallas Mavericks stole homecourt in game 2, beating the Oklahoma City Thunder in a 85-84 thriller, Mavericks fans are excited for game 3 in Dallas.  The game starts at 6 pm CDT (7 pm EST) and some people might arrive to the American Airlines arena a little late after leaving work.  Cuban posted a letter to excuse fans from work early so they can view his special, elaborate pregame speech.
