VERSE 1:
Em
I'm gonna save up all my bread

And put a bullet right in my dealer's head

Then I'm gonna steal all his whores

And buy myself a fastback convertible Porsche

    G                   Em
And go drinking down in Mexico  
        C                           D
Ask the Devil if I can have back my soul
    G               Em
And when things get better   
                C      D           G
I'm gonna write letters to let you know

VERSE 2:
Em    
Then I'm gonna get myself a pretty senorita

Who knows how to fight and drink tequila

She's gonna be pretty, pretty and stacked

Just like Charo flat on her back

Drinking down in Mexico

Asking the Devil if I can buy back my soul

And when things get better

I'm gonna write letters to everyone I know 
   
VERSE 3:

Well I'm gonna eat tacos, I'm gonna fly right

I just might still bark, but I sure won't bite

Under the moon on a Mexican night

Tell my friends I've seen the light

G                Em
Drinking down in Mexico

Ask the Devil if I can buy back my soul

And when things get better  
                       C      D          G
I'm gonna write em all letters to let em know
