Blake puts on the Ritz with style
After emerging from backstage carrying a Champagne glass, Shelton performs first with Taco's 1983 cover hit, "Puttin' on the Ritz" — and even does the tap dance featured in the video! Can we call this a toe-sync, too?

Gwen's mistaken call-out
"Jimmy Kimmel, thank you so much," Stefani tells Fallon before launching into Carly Rae Jepsen's 2011 hit "Call Me Maybe." But she makes it up to him by dancing quite close up with the host.

Gulp! Fallon brings Spike Jones into the 21st century
Unearthing a tune from 1944 by the musical comedy outfit Spike Jones and His City Slickers called "Cocktails for Two," Fallon had to imitate some hilarious vocalizations and sound effects.

Big Finale: Gwen and Blake's "Endless Love"
Yep, the pair shared the stage — and swapped roles. Stefani sang Lionel Richie's lines and Shelton belted Diana Ross's from the 1982 hit. Magic, sheer magic.
