Fox Trot Finesse

Storyline: Ferdie's wife is fox-trot crazy, wanting to go dancing all the time. To get out of it, Ferdie fakes an ankle injury. When his wife spies him walking without his crutch, she writes a letter to her stern mother, inviting her to stay with them while Ferdie heals. Rather than face his mother-in-law, Ferdie admits he was faking his injury, and tears up the letter.
