Everybody Loves Raymond - Season 5 Episode 9
Fighting In-Laws

While celebrating Thanksgiving, Debra discovers that her seemingly contented parents are really not very happy with each other. When Ray accidentally overhears his in-laws going at it with each other, he relays the news to Debra... who has always believed her parents relationship to be a lot healthier than Frank and Maries. But, when things come to a head at the Thanksgiving table, its apparent that there really isnt that much of a difference between the two older couples – much to Debras dismay.
