The less vicious of the two rumors started when someone thought a graphic of a ship pictured on Snapple's ice tea labels was a nefarious depiction of a slave ship, while in fact it represented the Boston Tea Party. Also, the small letter "K" enclosed in a small circle that appears next to the graphic supposedly represented a shorthand code for "Ku Klux Klan." In fact, it indicates that the product has been approved as kosher.
The rumors may have started because of Snapple's distinctive strategy of advertising on radio talk shows, which often feature stridently conservative hosts.
