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.''
