Solving other people's crossword puzzles...

Standing in line waiting to get on to the plane at Heathrow, I noted there were two British business men behind me. Not the CEO type, but the type that have little mustaches and are my height. They were talking about the crossword (which strangely in Britain is not the block of empty boxes interspersed with a few black squares familiar to us Yanks), and trying to solve a clue. Neither of the men could get it, and one said the clue "assumptive" and the other said "I have a_d_c_o__". Unable to help myself, I turned and said "Sorry, but its 'audacious.'" "But of course it is!" said the first man. "Jolly good one-upmanship!" said the other. I boarded the plane.
