Wiz Khalifa appeared on "Jimmy Kimmel Live!" last night, April 7th, to perform his hit song "Black & Yellow" while three nationally certified sign language interpreters competed in an epic sign language rap battle.  The three ladies took turns translating Wiz's lyrics into various signs, and added their own swag to the performance as they each danced along to the song while getting busy with their hands.  

It was a very close-fought sign language battle.  Check out who was victorious above, and let us know who you think should've won the battle.
