My sisters & I used to get the lyrics to songs mixed up all the time.
The GoGo's song "Our lips are sealed" we thought was "Alex the seal".
Billy Oceans song "When the goin gets tough" we thought was "Well go and get stuffed".(have a listen to it. It may be right!!!!)
The Australian anthem "Our home is girt by sea" we thought was "our home is dirt fly sea".
