In an argument with Kirstie, Leah Remini asks Kirstie, "Do I have Cheers money?" Leah Remini played Carlas oldest daughter in two episodes of Cheers, so in fact she does have Cheers money, just not as much as Kirstie.
Mayim Bialik, playing a fictionalized version of herself, recommends Kirstie try a diet plan by psychiatrist Sigmund Von Oy (played by Wallace Shawn.) In real life, Bialik co-starred with actress Jenn Von Oy on the show Blossom.
