The University of Manitoba recently conducted a research experiment to test the reliability of the maxim, "Kiss a Duck, Change Your Luck." They followed the fortunes of 100 subjects who were asked to kiss a duck every day for a week. Researchers then charted their luck for a period of three months. No significant improvement was observed. Some subjects even felt their luck had worsened, facial bites by ducks and lowered self-esteem being the most noted complaints.
