Lyrics
The Chipmunks:
Some guys have all the luck
Some guys have all the pain
Some guys get all the breaks
Some guys do nothing but complain
Alone in a crowd on a bus after work and I'm dreaming
The guy next to me has a girl in his arms, my arms are empty
How does it feel when the girl next to you says she loves you?
Seems so unfair when there's love everywhere, but there's none for me
Some guys have all the luck
Some guys have all the pain
Some guys get all the breaks
Some guys do nothing but complain
