Tonight Show host Jimmy Fallon had a little fun at the expense of his house band, The Roots, whose roots, of course, are in Philly.
Fallon taped the reactions of band members as they watched the viral new trailer for 50 Shades of Grey, a much-anticipated flick based on the kinky-sex bestseller.
But Fallon went further, to guarantee reaction.
"You know those scary faces that can sometimes pop up in YouTube videos? We added one," he said while introducing the video, which, as of Thursday morning, had gotten a half-million views.
