Justin Timberlake and Jimmy Fallon

Justin Timberlake closed out Season 36 of Saturday Night Live, reprising two memorable sketches — co-hosting "The Barry Gibb Talk Show" with SNL alum Jimmy Fallon and re-teaming with Andy Samberg for a third digital short in their '90s R&B group alter egos from "D--- in a Box" and "Motherlover."

Musical guest Lady Gaga also got to have some fun in "3-Way (The Golden Rule)," which saw Timberlake — who was serving as the show's host for the fourth time — and Samberg singing about how it's not gay if it's a three-way, "with a honey in the middle, there's some leeway." The clip also featured cameos from the duo's "Motherlover" co-stars, Susan Sarandon and Patricia Clarkson:

Timberlake played the Robyn to Fallon's Barry Gibb as the two pulled out their signature white suits, fake chest hair and crazy cool medallions to talk about "really important issues":
