Well that's just silly and no I've never heard of that.
Plus we broke almost all the rules for our wedding and loved it all so eff that noise. We even mentioned zombies in our ceremony. And I quote:
whitey & DJ, do you vow before all present here to love, honor, respect and support each other through good times and bad, through boon or bounty, to keep safe and sound through both physical and emotional experiences, including but not limited to zombie attack.
(he was supposed to say zombie apocalypse because we all know there's a big diff between an attack and the apocalypse but oh well, it got the point across, no?)
p.s. we are so awesome.
