The Voice coaches took a break from mentoring aspiring singers to showcase their talents earlier this week on The Tonight Show Starring Jimmy Fallon. During the segment, Fallon introduced the game Spin the Microphone, which he calls the musical version of Spin the Bottle.

The host then explained the rules to a less than enthused group of coaches. Essentially, once the microphone is spun, whoever's name the mic lands on, that person has to draw a card from the stack which has a song title on it. He or she then have the power to pick someone at the table to perform the song or they can perform it. Blake Shelton wasn't impressed, telling Fallon that it is the stupidest game he's ever heard of.

Gwen Stefani admits she's scared, but Adam Levine informs her that "this is not real." Unimpressed with the game, Levine becomes Fallon's first victim when he nominates the Maroon 5 frontman to sing Britney Spears' "Oops! ... I Did It Again." It's a lackluster performance at best, and when Stefani is selected to perform next she chooses Shelton to perform "YMCA." The country singer was a good sport and got the audience clapping along during his short performance, and he even did the arm motions for YMCA.

While the country star had the most enthusiastic performance, it was his duet with Gwen of Drake's "Hotline Bling" that was the most enjoyable and showed the two's chemistry. As Stefani rapped the lines, Shelton simply spoke "bling" into the microphone. Watch their performance above.
