What lyrics have you sung incorrectly until you actually looked them up?

Par exemple, I used to think that the chorus of AFI's "Miss Murder" went "Ham is my lufkan eye." Even though it didn't make sense, I sang it and it just rolled off the tongue. http://www.youtube.com/watch?v=W3wH6y6-7...
Haha, honestly, that's what it sounds like.
