The Black Keys attempt to reconnect to their blue-collar roots, in Bryan Schlam's uninhibited promo for Wild Child. 

In a riotous back-to-school concept, we see Patrick and Danny of the BKs take on a janitor and chef role at a high school full of drugs, fighting and various other disorderly behaviour. 

With a cast of teachers who are just as bad than the students - if not worse - all hell breaks loose when they take on their new roles. But will the Keys succeed to helps these kids, and these adults, become upstanding citizens? Er, no. But then, they can always go back to being rich rock stars... 

Playful and bawdy, Schlam packs out each scene with tonnes of laughs and gross-out humour, and the performances are spot-on all round. He's a master at this sort of thing.
