Batman
Nice hat, dork, you look like a duck
I had Alfred read your books, he told me they s**
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, b**h, I'm Batman
Sherlock Holmes
I once met a rich fellow who smelled of guano and pain (Holmes explain)
I deduce this deuce 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 sk**
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 you wonder how your a** got k**ed
Bite harder than those hounds down in Baskerville
I'll bust you with that bat-whack-rap repellant
Rappel a building, snatch a villain then by dinner be chilling
Gotta secret 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 goddamn
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
This mustn't register on an emotional level
First, exploit childhood tragedy, then gesture with pipe
Watson finishes punchline, next, acknowledge compliment
Conclude with k**er 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 pa**ive waste as momma died and daddy was dispatched with haste
(Holmes, you've cracked the case) You're a bat sh** crazy basket case
(Bloody good rhymes) I've got tonnes
Dissing these dynamic douchebags was elementary, my dear Watson
