Doc Brown vs Doctor Who

Rap Battles of History
DOC BROWN!
Versus
DOCTOR WHO!
Begin!

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!
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, well, never mind
Let's just say there's an infinite number of me simultaneously kicking your ass with rhymes!

Great Scott! 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!

I'm going to die...
Doctor...

At least, this version of me...

Doctor...

Perhaps you'd like another...

Doctor...

Prepare to meet your...
Density!
I'm a mystical medical doc 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 you're a pitiful hillbilly hangin' with an oedipal kid who's a BAWK BAWK chicken!

Nobody calls me chicken!

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!

Who won?
Who's next?
You Decide
