The legendary rock 'n' roll star behind the hit "The Twist" is suing Hewlett Packard over an app that measures penis size.

Chubby Checker (real name Ernest Evans) has filed suit in Saint Lucie County (Fla.) Federal Court this week, alleging that Hewlett Packard and its subsidiary Palm, Inc. didn't have permission to maintain the app called "The Chubby Checker."

According to a press release on MarketWatch, the 71-year-old's lawyer Willie Gary claims Hewlett Packard and Palm did not act quickly enough to take down the penis-measuring app, and that by doing so, damaged Checker's reputation:

"The "app" adversely affects Chubby Checker's brand and value and if allowed to continue, will cause serious damage to the Plaintiff's goodwill and will tarnish his image that he has worked to maintain over the last 50 years," the release states.

"Chubby" can be slang for a semi-erect penis.
