While "Tonight Show" band The Roots thought Jimmy Fallon was simply filming their reaction to the "Fifty Shades of Grey" trailer, there was something far more devious in the works. Fallon instead had a version of the trailer edited with a scary face and scream right in the middle of it.
The result was a very funny series of reactions. Bonus points go to Questlove though, as he went goes through a range of emotions very quickly; from confused by the trailer, to horrified and right into a fit of laughter.
