Macklemore then stands up and takes of his hood before busting out the song's rap.

The bus riders flash smiles when they realize what's happening. Some start clapping to the song while others record the performance on their phones. By the end of the clip, all of the bus riders are standing on their feet, dancing and rocking out to the hip-hop jam. Even the bus driver is clapping!

When the performance is over, everyone claps and cheers before the duo exit the bus. Too fun!

Macklemore and Ryan Lewis will also hit the stage to perform during the Grammys on Jan. 26.
