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
