Batman VS Sherlock Holmes

[Batman]
Nice hat, dork, you look like a duck
I had alfred read your books, he told me they suck
I'll crush your British nuts until they're bangers and mash
I've seen better detective work in Tango & Cash
You chump, I kick punks like you off the streets
While you and Velma here are solving Scooby Doo mysteries
Nothing makes me laugh, but I bet your raps can
So bring it on, bitch
I'm Batman!

[Sherlock Holmes & Dr. Watson]
I once met a rich fellow who smelled of guano and pain
Holmes explain!
I deduce this douce stain as bruce wayne
The billionaire?
Yes, his wealth would allow this adversary of ours
To afford the toys his needs
Since he has no superpowers!
You want to battle, bat? Bring it then
I heard he has a British butler
Good! Then he'll be used to getting served by englishmen!
You're a wack vigilante black pantied spud with no skill
My sidekick's a doctor
Because his flows are so ill!

[Batman]
Shut up, nerds, I serve justice, so eat it
My sidekick only comes around

[Robin]
When he's needed!
Boy wonder make a wonder how your ass got killed
Bite harder than those hounds down in Baskerville
I'll bust you with that bat whack rap repellant
Rappel a buildin', snatch a villain and by dinner be chilling
Gotta sing about your homegirl Irene Adler
Took her back to my nest to bam pow kersplat her
I'll shatter that fiddle with a chop of the hand!
Holy Conan Doyle, let's get 'em!
Aw God damn!

[Batman]
You're not smart, you're selfish, you endanger everyone's life
Why don't you let your boyfriend here go home to his wife?
Nobody likes you, not your brother, not your partner, not Scotland Yard
You'll die alone with no friends except that needle in your arm!

[Sherlock Holmes]
This mustn't register on an emotional level
First: Exploit childhood tragedy
Then gesture with pipe
Watson finishes punchline
Next: Acknowledge compliment
Conclude with killer catchphrase

I believe your parent's homicide is why you mask your face
You're shamed and traumatized
And haunted by the vast disgrace
Of watching like a passive waste
As momma died and daddy was dispatched with haste!

[Sherlock Holmes & Dr. Watson]
Holmes, you've cracked the case!
You're a bat shit crazy basket case!
Bloody good rhymes!
I've got tonnes!
Dissing these dynamic douchebags was
Elementary, my dear Watson
