Who knew selling insurance could be so popular? In 2000, insurance giant AFLAC started flooding the airwaves with the sounds of a snow-white duck repeatedly quacking "AFLAC" as human characters discuss supplemental insurance policies. For $10, fans can buy a miniature toy AFLAC duck, complete with a sound chip. Those who want to flee the squawking bird should steer clear of Japan: the AFLAC icon invaded in 2001.
