The table's all set, but Thanksgiving still won't go off without a hitch on Life in Pieces.

In the holiday-themed episode, airing Thursday around 8:30/7:30c on CBS, Joan (Dianne Wiest) has the entire family over for dinner, but also invites her recently widowed neighbor, Gary Timpkins to join. Guest star Martin Mull (Sabrina The Teenage Witch, Roseanne) plays Gary, who is prone to bringing up memories of his dead wife. Unfortunately, just as he begins to do so at the dinner table, everyone begins to have a strong, um, reaction to the cauliflower dish that Colleen (Angelique Cabral) brought.
