Avon Calling

An Avon Lady was delivering products in a high-rise and was riding in the elevator. Suddenly, she had the powerful urge to fart. Since no one was in the elevator, she let it go - and it was a doozy. 

Of course, the elevator then stopped at the next floor, so she quickly used some Avon Pine-Scented Spray to cover up the smell. A man entered the elevator and immediately made a face. "Holy cow! What's that smell?" 

"I don't know, sir. I don't smell anything. What does it smell like to you?" 

"Like someone crapped a Christmas tree."
