Passage of time

Gorse Fox has a task to perform. He has been asked to make a speech at an upcoming celebration for Betty and Barney Rubble who both attain their 60th birthday this year. This is difficult because preparing a speech worthy of the event is important - and of course because of his comparative youth, so much of their lives took place before he was around! Nevertheless, as a good student of history he will make every effort to get the tone and the historical facts right.
