Persian Fart

A woman walks into a shop that sells expensive Persian Rugs. She looks around and spots the perfect rug and walks over to inspect it. As she bends to feel the texture of the rug she accidentally breaks wind. Very embarrassed she looks around nervously to see if anyone has noticed her little accident. As she turns there standing next to her is a salesman.
“Good day M'am, how may we help you today?”
Very uncomfortable she asks, “Sir how much does this rug cost?”
He answers, “Lady if you farted just touching it, you're gonna shit your pants when you hear the price!”
