What about this one?
In the song by Yes called "Owner of a lonely heart", when they come to the part where they sing:
Owner of a lonely heart!
Owner of a lonely heart!
I used to think they tried to make people steal things from the lonely people on the street by singing:
Only rob the lonely ones!
Only rob the lonely ones!
Imagine that :D
