Excuse me, may I ask you a question?

So, there's this homeless woman in the city that does the rounds. Her schpeel begins, "Excuse me, may I ask you a question?" Yesterday, I had the pleasure of being one of her victims, while waiting on my bus to go to work. I get the prompted question and respond, "Sure," knowing where this was headed. I wait for the next bit, and she says, "I just wanted to ask, some people say no. Do you have any money..." I cut her off and said, "No, I have nothing, sorry." She turned away and mumbled, "Fucking liar." I caught her eye and responded in the driest way possible, "Fuck. Off." This totally got her panties in a wad, and she starting screaming at the top of her lungs--hurling every obscenity at me possible. I burst out laughing, looked her straight in the eye again and said, "Fuck. Off." At this point she was really spinning out of control and running down the street and turning back to scream more insults my way. My favourite, "Fucking poofter! You like it up the ass!" I just turned to the crowd standing around and said, "Good morning, all."
