I know a lot of people misconstrue song lyrics, but I tend to mis-hear them in an obscene or sexual way. For example, I've listened to Brenda Lee singing "Rockin' Around The Xmas Tree" on YouTube, and the fourth line really sounds like "later we'll have some fuckin' pie and we'll do some caroling". I think it's supposed to be "pumpkin pie", but my ears just don't hear it that way...
