Richie Whitt of the Star Telegram writes that the response to Mark Cuban's day as a Dairy Queen Manager was enormous.  A line curled out of the store and a half-mile down the street, with some people waiting an hour and a half to buy ice cream.  The Coppell Dairy Queen saw 6,000 patrons, eight news trucks and several helicopters.  Real DQ manager Parrish Chapman helped things along by renting a climbing wall and inflatable slides and having his employees wear Mavericks gear.
