A lady walks into a Porsche dealership. She browses around, then spots the perfect car and walks over to inspect it. As she bends to feel the fine leather upholstery, a loud fart escapes her. 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 was a salesman. "Good day, Madame. How may we help you today?"
Very uncomfortably, and to try and draw attention away to what she has just done, she asks, "Sir, what is the price of this lovely vehicle?" He answers, "Madame, if you farted just touching it, you are going to shit yourself when you hear the price!"
