Dean panics as he and Sheri prepare to renew marriage vows on their fifth anniversary, and he must pen promises as poetic as those he paid someone to write for the original ceremony. Panic grips Mel too, when he loses his wedding ring after telling Malena of his preference to go ringless. Meanwhile, Bobbi and Reggie seek a suitable mate for Thor/Chi-Chi, and a parade of canine hopefuls prance though the apartment.

As Mel and Malena's first wedding anniversary approaches, Mel wants to plan something truly memorable for the occasion. Dean warns him not to do anything that he cannot easily outdo next year. Malena's obsession with re-creating the night Mel proposed marriage--complete with the most insignificant details--threatens to disrupt the celebration. Meanwhile, after accidentally snacking on the ceremonial leftover piece of Mel and Malena's wedding cake, Reggie tries to atone by helping Sheri bake a new cake to match it.
