*Short Bass intro*
G 
Why do you try to cheat and trample people under your feet?
                     C
Don't you know it is wrong to cheat a trying man?
                     G
Don't you know it is wrong to cheat a trying man?
           D                     G 
You better stop, it is the wrong 'em boyo

You lie, steal, cheat and deceit
It's such a small, small game

Don't you know it is wrong to cheat a trying man?
Don't you know it is wrong to cheat a trying man?
You better stop, it is the wrong 'em boyo

(Hey, it's the wrong 'em boyo)

Billy Boy has been shot and Stagger Lee's come out on top
Don't you know it is wrong to cheat a trying man?
Don't you know it is wrong to cheat Stagger man?
You'd better stop, it is the wrong 'em boyo
You must start all over again, all over again
Don't you know it is wrong?
Play it Billy, play, (Don't you know that it is wrong?) Play it Billy, play
And you will find it is the right 'em boyo (Hugs)
But if you must lie and deceit and trample people under your feet
Don't you know it is wrong to cheat a trying man
Don't you know it is wrong to cheat a trying man?
You'd better stop, it is the wrong 'em boyo, it is the wrong 'em boyo, it is the wrong 'em boyo
It is the wrong 'em boyo, wrong 'em boyo, it is the wrong 'em boyo
