    "What's your name?"

    "Hillary. It means 'She whose breasts defy gravity'. What's yours?"

    "Nick."

    "'Nick'? What kind of name is that?"

    "Oh, it's just something my father thought up while he was shaving."

    /please tell me that's not obscure

    The pilot and main jets are smaller then my 650's are.
