Karma is a vengeful woman 

and I dare say so am I

One minute smiling at nothing

the next laughing maniacally to the sky

This is how it goes with me

You dis me, I dis you

 It's how the saying goes after all 

an eye for an eye, a tooth for a tooth

 Karma and I, we're good friends 

 as you have plainly seen

We walk the same and talk the same

And have the same rules you're wise to heed
