An air freshener salesman goes to an executive building to market his product to a prospective buyer. He steps in to an empty elevator and presses the tenth floor button. Just as the doors close, he lets out an awful fart.

The elevator stops on the fifth floor, so he quickly sprays his new "Pine-Scented" air freshener to cover his tracks. The doors open and a man steps onto the elevator.

The salesman figures this is a good opportunity to test his product's quality, so he says, "Excuse me sir, could you kindly tell me what you smell?"

The man replies, "Yeah, smells like someone shit a Christmas Tree."
