I'm gonna tell you a story
'Bout ol' Mary Lou
I mean the kind of a girl
That make a fool of you
 
She make a young man old
And an old man pay
The way she took my money
Was a crying shame
 
Mary Lou, Mary Lou
She took my watch and chain
Mary Lou, Mary Lou
She took my diamond ring
She took the keys to my Cadillac car
Jumped in my Caddy and she drove afar
 
Put a detective
On her trail
The post office thought
They'd chase her by the mail
 
She got picked up
And then was put in jail
Stroked the judge
Just to go her bail
 
Mary Lou, Mary Lou
She took my watch and chain
Mary Lou, Mary Lou
She took my diamond ring
She took the keys to my Cadillac car
Jumped in my Caddy and she drove afar
 
She left Detroit
To go to Kalamazoo
Made her a fortune
Out of fools like you
 
Met her a rich man
Who was married and had some kids
Stroked that cat
Until he flipped his lid
 
Mary Lou, Mary Lou
She took my watch and chain
Mary Lou, Mary Lou
She took my diamond ring
She took the keys to my Cadillac car
Jumped in my Caddy and she drove afar
 
She came back into town
About a week ago
Told me she's sorry
She had hurt me so
 
I had a '65 Ford
And a two dollar bill
The way she took that
Lord, it gave me a thrill
 
Mary Lou
She took my watch and chain
Mary Lou, Mary Lou
She took my diamond ring
She took the keys to my Cadillac car
Jumped in my Caddy and she drove afar
