Security Ninja

My grandpa runs this store, and he had trouble with thugs loitering around outside, chilling out, selling drugs, and basically chasing away all of his customers. So he hired this security guard who is also a Ninja. When the thugs came around, the Ninja politely asked them to leave in a thick Japanese accent, and when they laughed at him, he went nuts with a pair of nunchucks and put half of them in the hospital. The whole neighborhood heard about it, and now anytime there's someone loitering outside the store, my grandpa dresses me in a Ninja outfit and I ask them to leave in a fake Japanese accent.
