A common TV series pitch--or parody of one--is taking an "odd couple" and placing in them in situations where they solve mysteries and defeat criminals. This trope is called They Fight Crime, and examples include Numb3rs ("He's an FBI agent; he's a math professor. They Fight Crime!") and Blood Ties ("She's a Canadian police detective who is slowly losing her sight. He's a vampire. They fight crime!").
From Jaka, there's this neat meme:
1.) Go to TheyFightCrime! and find a crimefighting pair that makes you swoon.
2.) Go to the Hero Machine and illustrate your duo!
3.) Repeat as necessary or until your mom tells you it's time for bed.
I'll illustrate one I did, but first, guess this famous media property. You'll be surprised who it is--I certainly was! Answer after the images below:
"He's a battle-scarred veteran of the war in Afghanistan! He's a substance-abusing dilettante grad student! They Fight Crime!"
|"He's a leather-clad guitar-strumming photographer who believes he can never love again. She's a virginal insomniac bounty hunter who hides her beauty behind a pair of thick-framed spectacles. They fight crime!"|
And the odd couple mentioned above?
Dr. Watson and Sherlock Holmes.
