I DON'T THINK MY GAL LOVES ME ANYMORE
(As sung by Homer & Jethro)

She hit me on the head and she tore my clothes.
She blacked my eye and broke my nose.
I don't think my girl loves me anymore.
She changed her front-door lock, you see,
And then she sic'ed her dog on me.
I don't think my girl loves me anymore.
Well, I caught her in the kitchen
Puttin' arsenic in my tea,
And if she doesn't cut it out,
I'll think she's mad at me.
And when our date last night was through,
She said, "Don't call me. I'll call you."
I don't think my girl loves me anymore.

Now when I call her on the phone,
She answers and says that she's not home.
I don't think my girl loves me anymore.
She shoves me down the stairs and counts
To see how many times I bounce.
I don't think my girl loves me anymore.
Well, I caught her foolin' with the brakes
Beneath my car today.
Aw, jeez, that's awful nice of her
To fix my car that way.
She's got a rifle now, I see,
And it's a-pointin' right at me.
I don't think my girl loves me anymore.
I don't think my girl loves me anymore.

[Recorded by Homer & Jethro on "Life Can Be Miserable," 1958.]
