breaking wind

A woman in a jewelers breaks wind bending over to look at a beautiful diamond ring. She looks round, embarrassed, and sees the salesman standing right behind her. Totally professional, he says “good day madam, how may I help you?” Hoping he maybe hadn’t heard her ‘accident’, she asks “sir, what’s the price of this lovely ring?” He answers, “madam, if you farted just looking at it, you’re going to shit yourself when I tell you the price!”
