LMFAO music artist's have a music video / song where people have become zombies to the music, the "infection" spreads into your bones and will make you "shuffle" along with the rest of the zombies.
The pair wake up in abandoned hospital beds and as they walk out of the front door are approached by a healthy non infected fellow human. He warns them, play along and do the shuffle dance, or they will notice you are not one of them.
The song is called " Party Rock Anthem" by LMFAO.
