Last February, rock-and-roll legend Chubby Checker sued the companies, asking for $500,000 while claiming the third-party app called the Chubby Checker adversely affects Chubby Checkers brand and value. The app itself, which was first released in 2006, would estimate penis length from whatever shoe size was inputted. Nonetheless, Chubby Checker — whose real name is Ernest Evans — went after the companies, arguing that the app infringed on a number of his trademarks.
