Somehow, NOT because of a case, Sherlock has to work as a cop or a police detective for the Yard under poor Greg (because nobody else will take him.) Either because of probation, Mycroft, etc. he has to make this his semi temporary job instead of free lance.
Sherlock is of course not happy and causes everything from collateral damage, stealing donuts, to restraining orders at work. The Yard wants to fire him but 1)Can't because of Mycroft and 2)He's actually better now that he has first dibs on crime scenes.
Bonus: A police car chase and the reason why Sherlock doesn't drive.
Bonus 2: A criminal thinks he's a whump and Sherlock shows him wrong.
Non cracky but humorous AU: Sherlock is an actual cop/police detective
