S1, E19: Judith's sinister-but-sexy sister, Liz (TERI HATCHER - "Lois & Clark: The New Adventures of Superman," "Tomorrow Never Dies"), plans to attend Jake's 11th birthday party. Alan asks Charlie--who had sex with Liz in the coatroom at Judith and Alan's wedding--to behave. But when Liz arrives, she ignores Charlie and flirts with Alan instead. Liz proceeds to cause a commotion between her sister, whom she's never really gotten along with, and her ex-brother-in- law. Meanwhile, Evelyn forgets that it's cake, not alcohol, that's traditionally served at a child's birthday party, and she proceeds to party her own way.
