Revealing mistake: When Chloe (the new hire) and Janet are talking on the couch near the end, water spots suddenly appear on Chloe's shirt, indicating the actress was lactating while filming.
Suggested correction: Just because it was never mentioned in the storyline of the show, there is no reason Chloe couldn't have a baby at home thus causing the lactating.
Sorry, but the wording in this correction is confusing. Agreed, there was no mention in the show of Chloe having any baby at home. So very well, she may have been lactating, which explains the sudden water spots as mentioned.
Revealing mistake: After Chrissy purposely spills the wine onto her married date's lap, he raises the glass, and it's cleverly covered in saran wrap, so that the glass pieces don't go flying when she breaks it with hers.
Jack in the Flower Shop - S2-E19
Revealing mistake: Once Jack arrives home from his first day, Janet follows shortly behind him with her arms full of groceries. She hands the bag to Chrissy but watch at the bottom of the bag - it starts to come apart and Chrissy grabs the bottom of it and holds it together. The end sight gag is that when Jack storms out, and Janet storms off, Chrissy then goes to go to the kitchen, and the groceries fall out of the bag at the bottom - but it's because then she's holding the bag then around the center.
Revealing mistake: The lights around the stage reflect in Jim Walsh's sunglasses a few times.
