Kendrick Lamar was the musical guest on last night's "Saturday Night Live", the sixth episode of the 40th season hosted by Woody Harrelson. Earlier this week, he took a piggy-back ride on Harrelson in lieu of public transportation; last night, he performed "i" (while sporting some scary contact lenses), as well as his Jay Rock collab "Pay For It". He also appeared as himself in a sketch called "Young Tarts & Old Farts", a fake advertisement for a compilation album of covers between young up-and-comers and established artists (such Ariana Grande with Lionel Richie, Elton John with Blue Ivy Carter, and Aretha Franklin and Robyn); Lamar was paired with Taran Killam's Barry Manilow. Watch everything below.
