Are These Sexually Suggestive Lines From 50 Cent Or 'Fifty Shades Of Grey'? Watch And Decide

It's not as easy to figure out as you might have thought.

Would you be able to tell the difference between a 50 Cent lyric and an except from the book "Fifty Shades of Grey" -- if 50 himself was reciting the lines?

That's the question that was posed to the audience -- and, in particular, two contestants -- during the rapper's recent appearance on "The Meredith Viera Show."

Fif -- in a deep, sensual voice -- delivered brief couplets from each, and the contestants had to decide if they were from the platinum-selling artist's music, or the best-selling 2011 novel. And they knew their stuff.

"I can't believe you all read this book!" 50 exclaimed, half-amused, half-exasperated. "How do you remember every word that was in the book?"

The last one was probably the best. "I touched the right spot at the right time," Fif said.

"He found the spot!" Meredith yelled, before dropping to the floor.

He's still got it.
