LUCY: Ethel, give me one good reason why I can't play the lead.
ETHEL: You can't carry a tune.
LUCY: (shocked) Well!
ETHEL: Well it's true! Watch.
(ETHEL proceeds to sing a successful series of notes and trills.) Now you.
(LUCY, nervous, produces a few shaky, off-key notes before modulating into "I've Been Working On The Railroad.")
LUCY: (after her song diminishes to nothing) Okay. Where do I go to get my teeth snaggled?
