Quiz Week!! continues with a graduate-level Elvis exam. This installment comes from a past issue of mental_floss magazine, and it’s really, really hard. I’m not sure Lisa Marie would break 60%. But if you’re an Elvis aficionado, test your knowledge of the King’s co-stars.

Take the quiz: All the King’s Co-stars.

And if you’re not an Elvis fan, we’ve got plenty of other quizzes for your amusement.
