Have your way with me

I'm crazy for you, I'm insane.
I'll do anything that you say.
Perform all your services for free.
If you have a need, I'll fill it.
If you have a pain, I'll kill it.
The one for the job exclusively.
Have your way with me.
Anything you want me to do.
Bend over backwards just for you.
Any chore: complex or easy.
Feel free to put me to the test.
Can out-perform the very best.
And with a cash back guarantee.
I'm crazy for you, I'm insane.
I'll do anything that you say.
Adaptable and installed for free.
Have your way with me.
