Motherlover premiered as a Saturday Night Live digital short in May 2009, written and performed by The Lonely Island with Justin Timberlake returning alongside Andy Samberg. It was a Mother's Day sequel to their earlier Dick in a Box characters, with the pair singing a sincere tribute that spirals into proposing they date each other's mothers. The short went viral on early YouTube, was later released as a single, and the step father payoff became one of its most quoted and clipped moments for family-themed memes.
