So Jimmy Fallon, who tapes his show right across from the popular singing competition ‘The Voice’ decided to prank the coaches by ‘auditioning’ for the show.

Host Carson Daly told viewers he had a “special surprise” for them before Fallon appeared onstage.

“Right now, we have an artist backstage preparing for the biggest performance of their entire life,” he said, teasing the surprise guest.

Fallon then joined the stage to sing 1982’s “I Keep Forgettin’ (Every Time You’re Near)” by Michael McDonald, at least, that’s what he said he was singing.

Watch what happens.
