The more I thought about it, the better I liked the idea. The corps de ballet were already calling me "the Phantom of the Opera," an intriguing sobriquet which appealed to me very strongly, until I realized that it would mean signing my ransom notes P. T. O. One did not wish to descend to the ridiculous!
O. G. I became and O. G. I have remained.
But I still liked to think of myself as the Phantom.
