The "Return the Slab" episode revolves around a seemingly trivial plot: Frasier's (Kelsey Grammer) mother's, Joy's (Jane Leeves), favorite coffee table, known as "the slab," has been taken away by a furniture repossession company due to unpaid bills. However, this setup quickly evolves into a complex web of relationships, egos, and comedic misunderstandings. The episode expertly weaves together multiple storylines, including Frasier's attempts to retrieve the slab, Niles's (David Hyde Pierce) romantic misadventures, and Martin's (John Mahoney) gruff but lovable interactions with his son.
