Very embarrassed, she looks around nervously to see if anyone has noticed her little accident and hopes a sales person doesn't pop up right now.
As she turns back, there standing next to her, is a salesman. "Good day, Madame. How may we help you today?"
Very uncomfortably she asks, "Sir, what is the price of this lovely vehicle?"
He answers, "Madame, if you farted just touching it, you are going to sh*t when you hear the price."
