History
When Mary saw Betty being surrounded by men whilst playing piano badly, she asked Betty how she did it. Betty told Mary that she never took a piano lesson in her life and she was tone deaf. She went on to tell Mary that she ordered the E-Z Entertainer Guidebook to get around not having any musical talent. Mary then ordered the guide herself and also had men surround her whilst she played piano badly.
