“...this same performance in Philadelphia could have been the one that was followed, as Cable remembered it, by Twain's rueful groaning, 'Oh, Cable, I am demeaning myself. I am allowing myself to be a mere buffoon. It's ghastly. I can't endure it any longer.' That night and the next day, according to Cable, Twain devoted himself to the study and rehearsal of selections which he deemed justified both as humor and as 'literature and art'”. (pg25 Cardwell)
