Perhaps you are aware of Jonathan Coulton, his associations with John Hodgman, or even his Thing A Week.
But have you heard his brilliantly hilarious song RE: Your Brains?
As someone who loves both Jonathan Coulton and zombies, I highly recommend the song, which is easily my favorite of his Things A Week. Just click on ‘re your brains’ towards the bottom to hear it—you know, if you aren’t afraid of having it stuck in your head the rest of the day.
