Doug!  Doug!  The building's on fire! 'Oh, hi Perry.  Say, would you look over this report for me?'  You don't understand!  We're going to be engulfed in flames any minute!  'Uh-huh?'  We've got to get to the helicopter on the roof!  'Look!  I'm busy.  Either help me with this or let me do my work.'  'What's going on here?'  Oh Chuck, we've got to get out!  The building's on fire!
