There once was a Bald Man who sat down after work on a hot summer's day. A Fly came up and kept buzzing about his bald pate, and stinging him from time to time. The Man aimed a blow at his little enemy, but - whack - his palm come on his own head instead again the Fly tormented him, but this time the Man was wiser and said ''YOU WILL ONLY INJURE YOURSELF IF YOU TAKE NOTICE OF DISPICABLE ENEMIES.''
