Ever have some really dumb song stick in your head? Of course you do, everybody does. Well, I have this particular song that I can't get rid of and I'm certain that my mind is replaying the wrong lyrics anyway (you know how you just make shit up when you don't really know the words..)
So help me figure out the right words here, I wish I could remember who sings it....

'Blinded by the light, wrapped up like a (here's where I get fucked up) douche, another runner in the night....'

Ok. I know the guy's not saying douche there, but that's what it sounds like. And if he IS saying douche - why?
Help.
