We used to live a life so cloistered
Where all of us were foisted
With stuffy robes and endless regulations
Now here he is again
Both enemy and friend
The same old fool in every regeneration
I'm never one to advocate being boring
'Cos it's not polite to leave a lady snoring
But some things I won't change, not even if I could
Oh, I have not turned good
You humans are misguided
And oh so narrow-minded
The Doctor gives you more than your due credit
Get back to your souffle
And don't get in my way
I wouldn't have you here if I could help it
He's lying if he says I'm not his greatest rival
(Admittedly the Daleks are more genocidal,)
But some things I won't change, not even if I could
Oh, I have not turned good
I'll always find it thrilling
The teasing and the killing
There's nothing you can do to ever stop me
Oh Clara, don't you know?
It's not you who runs the show
You are nothing but a puppy on a lead
Please donnae be fooled by my sweet appearance
'Cos I will not tolerate your interference
Some things I won't change, not even if I could
Oh, I have not turned good
I'm M-M-M-M-Missy
Causing m-m-m-m-mischief
Not dead. Surprise! Looks like I had you fooled
So what if I try to kill him?
He tries to kill me too
Is that not what best friends do?
So it might be true that I'm a bit eccentric
And my motivation is the Doctor's friendship
But some things I won't change, not even if I could
Oh, I have not turned good
