 The rift between Martin and his sons  tastes is bridged when they find they are all fans of "The Antique Roadshow." The boys have a great time watching it on TV, and when the Roadshow comes to Seattle, they all go. Martin takes along an old family heirloom, a rather ugly pewter clock. Frasier and Niles are stunned to hear that it was originally made for the Romanovs (the Russian royal dynasty). Believing the clock is a link to their own royal blood, Frasier and Niles launch an investigation into its origins. What they find is that the clock was stolen by their great-grandmother, a kitchen maid. Since it was stolen, the Russian government takes it back; since Martin has already been promised $30,000 by another buyer, Frasier and Niles have no choice but to put up the money, which Martin uses to buy a Winnebago.
