So when I first heard the song "I Will Follow You Into the Dark" by Death Cab for Cutie, there was a line where I wasn't so sure what he was saying. I heard:
"If heaven and hell decide that they both are satisfied
Illuminate the nose on their Vatican seasides"
Eventually I looked this up on a lyrics website. Turns out the actual lyrics are:
"If heaven and hell decide that they both are satisfied
Illuminate the no's on their vacancy signs"
whoops.
