Doc brown vs doctor who

[Doctor Who]
Ooh, actually, if you don't mind, it's just The Doctor
Doesn't even really matter who
Who am I even talking to? Oh yes, you!
The wannabe Einstein, minus the 'stache
Travels through time, but with no class
I'm saving the world while you dilly-dally
You can't even invent your way out of Hill Valley!
And calm down! Will you?
Everything is going to be fine!
You're not going to tear any wonky holes in any fabric of space and time
Actually, it's a lot more like a rug, really, oh, well, never mind
Let's just say there's an infinite number of me
Simultaneously kicking your ass with rhymes!

[Doc Brown]
Great God! You're great
Not!
I spit it hot
And generate way more power than 1.21 gigawatts
I'm not sure what sort of scientific authority you purport to be
But I'm a real doctor!
Where'd you get your degree?
Despite all your companions you couldn't be having less sex
I don't know what's lamer: Your fans or your special effects!
You don't get another turn to debate, time to face your permanent fate!
Now, Dalek my balls!
Exterminate!

[Doctor Who]
I'm going to die
At least, this version of me
Perhaps you'd like another
Prepare to meet your

Density! Hahahaha!
I'm a mystical medical dog at the pinnacle shifting my physical form
You're a possibly pedophiliac individual who should've never been born!
You got your knickers in a twist while you're sucking on my piccadilly
But I'm a lot lot different
Cause your a pitiful hillbilly hangin' with an edible kid who's a bawk bawk chicken!

[Marty McFly]
Nobody calls me chicken!

[Doc Brown]
This is between us, scarfy! Don't try to outrhyme me
You'll find I'm as grimy as any slimy time limey
I'll use your porta-potty time machine as my latrine
You're not a cat with nine lives, you're a pussy with thirteen!

[Doctor Who]
Ooh, actually, if you don't mind, it's just The Doctor
