NY state of mind

One of my favorite stories my dad told me from when he was growing up:

Him and a friend were walking home from school, when out of nowhere a dude jumps from around the corner and yells "GIMME YA MONEY"
My dad's friend asks, "Do you have a gun?"
The criminal replies "No."
My dad's friend asks, "Do you have a knife?"
The criminal replies again,"No"
My dad's friend says "Well nigga you better get out our face before WE ROB YOU! This is Harlem!"...
