You're a real tough cookie
With a long history
Of breaking little hearts like the one in me
That's okay, lets see how you do it
Put up your dukes, let's get down to it
Hit me with your best shot
Why don't you hit me with your best shot
Hit me with your best shot
Fire away
You come on with the come on
You don't fight fair
That's okay, see if I care!
Knock me down, it's all in vain
I get right back up on my feet again!
Hit me with your best shot
Why don't you hit me with your best shot
Hit me with your best shot
Fire away
You're a real tough cookie with a long history
Of breaking little hearts like the one in me
Before I put another notch in my lipstick case
You better make sure you put me in my place!
Hit me with your best shot...
C'mon!
Hit me with your best shot...
Hit me with your best shot
Fire away!
Hit me with your best shot
Why don't you hit me with your best shot
Hit me with your best shot
Fire away
