Tina is hosting Thanksgiving dinner, and Brad invites Larry, Henry and Amanda to join them, since Tina's mother Nanette (guest star Jessica Walter) and sister Alicia (guest star Laura Bell Bundy) are in town for the holiday. Despite trying, Brad can't seem to make a good impression on Nanette, especially after Henry has to fend off Nanette's advances. Meanwhile, Larry mistakenly calls Alicia "Tina" during a make-out session, and Amanda gets very defensive about her femininity.
