With a photo of Williams from Mork & Mindy, The Roots drummer started his Instagram post by writing, "Man. The smallest gesture can mean the world to you. Robin Williams made such an impact on me and didn't even know it."

Questlove explains that at the 2001 GRAMMYS, Williams got into the elevator with the Roots and "named checked all of us." Questlove says the band had to ride the elevator to the backstage area and they all piled inside. "When suddenly this voice just said 'questlove�..black thought�.rahzel�.the roots from Philadelphia!!!!' That's right you walked on this elevator saying to yourself 'ain't no way this old white dude knows my entire history and discography'�.we laughed so hard. That NEVER happened to [us] before," he wrote.
