It's the last episode of SNL this year and the crew ensured audiences of a star studded show including Madonna, Paul McCartney, Barry Gibb and even Mayor Bloomberg!

The last episode for this year's Saturday Night Live hit off with Fallon and Timberlake's "wrap rap." The rap medley performance had the hilarious duo dressed up as presents with Timberlake predominantly in red and Fallon in a greenish ensemble. Their sense of fashion was topped off with humungous white gloves and a scenic street-alley setting which brings back memories of Timberlake's dancing mascot days.

Since their beloved guests were "reportedly" stuck in traffic, Fallon had to spread "Joy to the World" on his own - at least initially.

"Unfortunately they can't be here. Traffic is tough at this time of year and all of them are currently stuck in the Lincoln Tunnel," the future Tonight Show host told the audience.

Though Fallon did save his opening monologue somehow, Paul McCartney's sudden appearance did the spiel good. It seems that the Beatles singer took his Citi Bike to ditch traffic in time to perform "Have Yourself a Merry Little Christmas" with Fallon.

Madonna also joined the duo as a guest for the 'Barry Gibb Talk Show' where the queen of pop herself talked about politics among several other things and her bling-ed teeth. The real Barry Gibb also joined Fallon and Timberlake in the sketch's first run after Robin Gibb passed away last year.

Timberlake appeared as Fallon in a spoof of the host's guesting gig at Family Feud - stacking NBC stars against those from CBS. Fallon played CBS' Jim Parsons.

The other hilarious rap performance for the night was delivered by Fallon himself. The future Tonight Show host expressed thoughts on the struggles of getting laid while on a family holiday.

Watch "(Do It On My) Twin Bed" featuring SNL's very own girls.

Timberlake also took the stage, complete with a laser light show to the tune of "Only When I WalkAway."

Check out other equally entertaining parts of SNL's last episode like the Kimye (Kim and Kanye) Talk Show, Cecily Strong and Fallon's 'Baby It's Cold Outside' performance and Weekend Update by Mayor Michael Bloomberg, Seth Myers and Fallon.
