WASHINGTON — A lawyer acting for Chubby Checker — the musical legend behind “The Twist” — has announced a lawsuit against tech-giant Hewlett-Packard for using the singer’s name for a penis-measuring app.

 In a statement this week, attorney Willie Gary said the suit named HP and its subsidiary Palm, for marketing the software application without permission.

 The suit filed a Florida federal court seeks $500 million in damages.

 According to Gary, it alleges the app “adversely affects Chubby Checker’s brand and value...

and will tarnish his image that he has worked to maintain over the last 50 years...

 The defendants have marketed Chubby Checker’s name on their product to gain a profit and this just isn’t right.”  The “Chubby Checker” app, which appears on websites for Palm devices, claims to allow a person to determine a man’s penis size by using his shoe size.

 Checker, 71, is best known for his 1960 hit “The Twist” which spawned a dance craze.
