Jimmy Fallon knows the whole world collectively freaked when the first 'Fifty Shades of Grey' trailer dropped, so of course, he couldn't resist playing a little 'Fifty Shades' prank on his in-house band the Roots.

Fallon decided to film the guys' reactions to the trailer, which, unbeknownst to them, was edited to feature a hilariously terrifying face popping out and screaming in the middle of it. Needless to say, their reactions are pretty freaking priceless, complete with horrified looks, high-pitched shrieks and uncontrollable laughter. (Of course, for some, this may just been their reaction to the trailer even without the scary face.)

Because a description just can't do it justice, take our word for it and check out the Roots LOL-worthy reaction to Jimmy Fallon's 'Fifty Shades of Grey' prank in the video above! We guarantee you'll laugh aloud -- and maybe even enjoy it even more than the original trailer.
