There were some familiar skits — Timberlake's infamous "Homelessville" number from 2006 was rebranded as "Wrappinville," with Fallon stepping in to duet with the singer. (Of course.) "The Barry Gibb Talk Show" also inevitably reared its head and even featured a surprise cameo from Madonna as well as the Bee Gees legend himself, Barry Gibb. The "Now That's What I Call Christmas" skit packed a few laughs (as well as Lorde's first official SNL parody — she's made it!), while Paul McCartney's merry Chipmunk caroling with Fallon was charming (and obviously made Fallon's life complete).
