Season 3: Episode 53: Kim's New Nanny
When Kim arranges a playdate with one of Sam's classmates, she's in for a big surprise when the girl's mother, Jessica, drops off her child - she drops off her sweet, elderly nanny, Sylvia, too. Angry about her uninvited guest, Kim ignores Sylvia at first, but when she changes her mind and gives her the time of day, Sylvia lets her know that Jessica yells at her all the time. She's just afraid to speak out against Jessica for fear of getting fired. After Jessica returns to pick up her kid and Kim witnesses her yelling at Sylvia, she tells Jessica off and asks Sylvia to come to work for her instead. But no sooner than the new nanny starts work than Kim figures out why Sylvia got yelled at -- she's incompetent. Yet Kim feels so bad for Sylvia that she can't bring herself to fire her. At least not until she discovers how many other mothers have had her and how they all managed to get rid of her. Meanwhile, when Jimmy buys a robotic dog for Dominic and then accidentally ruins it when he leaves it outside near the sprinklers, Dominic can't seem to part with the broken toy -- which reminds Jimmy of his childhood dog.
