We finally know why NBC cut parts of the “Fifty Shades of Grey” trailer when they premiered it last week. It’s scary as hell!

On Tuesday’s “Tonight Show,” Jimmy Fallon had The Roots watch the trailer that has been called “too hot for TV” to get their reactions, but the catch is he added a scary face that pops up in the middle of the video.

It’s slightly cruel, completely unexpected and totally hilarious.

“The Tonight Show Starring Jimmy Fallon” airs weeknights at 11:35 p.m. ET on NBC.
