What is Carroll Shelby famous for?
user
She designed the legendary Ford Mustang.
assistant
Carroll is actually a he.

Yes, I know that he and the other famous person, Carroll Keaton, are both men.  The database I was using had “Carroll” and “Carroll Shelby” listed separately, rather than as a single person, and that lead to some misunderstandings. I am sorry for that.
