Continuity mistake: When Caryn is on the desk, her back is to the class. After the pledge, when Dick says "never mind" and the camera angle changes, she's now facing the class.
Continuity mistake: The devil horns, mustache and goatee that Tommy spray paints on the picture of Harry change appearance between shots. (00:16:40 - 00:17:15)
Answer: The writers often have Dick respond to Mary with a retort that he thinks is in the common vernacular but makes a mistake in wording that is often funny. Dick seems to be imputing a criticism from Mary and responds with a corruption of the more common "I'm going to wear your ass like a hat!" I doubt it has anything to do with owing taxes. Probably just one of the writers assuming a common regional phrase would be universally recognized.
That makes total sense. I always interpreted it as perhaps snowshoes are an expensive item, and given that he was blaming Mary for his newfound financial woes, he was equating her living off his generosity and used snowshoeing as a metaphor.
