My landlord tried to hold onto my deposit unfairly, though I vacated the apartmentl on time and left it in good condition, but he backed down when I told him that I had studied Kung-Jew.
It involves letting out some kind of jew cry while throwing spare change at the offender like throwing stars. While they are ditracted you lay down a whoopin' with your money packed wallet/purse untill they are unconscious(One hit should do the trick),then publicly humiliate them in anyway you see fit
"Dude that man insulted my beard, i'm gonna go kung jew the shit out of him!"
Jew 1: "Dude you totally kung jewed that kid's ass on the playground!"
Jew 2: "I know!"
