I prefer the oath offered by Jack Douglas, author of epic works including "Never Trust A Naked Bus Driver", "My Brother Was an Only Child" and the story of his family's move to Alaska, "Shut Up And Eat Your Snowshoes."
That oath: "I am not now and never have been."
Works for me.
Somebody else remembers Jack Douglas! I used to watch Jack and Reiko on Jack Paar and then Carson. Always fun.
Reiko passed away recently, Jack's been gone a long time.
Anyway, on the subject of oaths, let's not forget the Minimalist Bass Player's Oath: I promise to play the root, the whole root, and nothing but the root, so help me Dusty Hill.
