Upcoming Saturday Night Live host and The Voice coach Blake Shelton stopped by The Tonight Show Thursday — and his visit turned into a bit of a concert. But the person singing was not, in fact, Blake Shelton, but instead Jimmy Fallon, who attempted to sing some of Shelton’s hits. Watch as Fallon totally butchers “Neon Light” and “Boys ‘Round Here,” with accompaniment from house band The Roots. After Fallon attempted to impress Shelton by essentially ruining his songs, Shelton looks into Fallon’s eyes, smiles his charming Blake Shelton smile, and drawls, “I seriously can’t stand you.”
