Fallout Boy - Sugar We're Going Down
'Lie in the grass next to the mausoleum.'
I heard it as:
'Line on your ass, next to the Mona Lisa.'
There's a few videos on YouTube about this, titled 'Misheard Lyrics'. The one for O Fortuna is hilarious, and there's an absolutely perfect one for Zetsubou Billy Occasionally, when I'm not really listening, I hear weird things in songs. For example, the singer will say something nail-bitingly filthy and I'll be the only one to hear it, whilst everyone else hears what they actually sang which is actually completely innocent.
