Killam was a member of the Los Angeles-based improvisational and sketch comedy troupe The Groundlings.
During a late-night writing session for SNL, Killam decided to recreate the video for "Call Your Girlfriend" by that week's musical guest, Robyn, in the writer's room; the iPhone video of Killam's dance routine quickly went viral.
A 2012 video sketch starring Killam and Kenan Thompson, "Mokiki and the Sloppy Swish," was the first SNL music video to go viral after the departure of The Lonely Island the season before.
