This Little Dick Goes to Market - S5-E14
Trivia: When Dick and Tommy walk through the Eversoll office, the door they open up has the name "Gary Parkinson." Gary was the Buckeye Fidelity insurance salesman from s05e03, "The Fifth Solomon." They also pass the office of "Ted Hughes." Ted also worked at Buckeye. Terry Hughes was the director of the episode.
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.
