Any great ideas for a 'stage name'?

A lot of current actresses who have stage names use a middle name or a relatives name. They generally do not change it entirely anymore. Mostly, they drop their last name if it is a mouthful or hard to pronounce and use their middle name, such as Lea Michele. Or they change their name to something similar like Ringo Starr. And some change their last name to simple or American sounding names like Dean Martin.
