Revealing mistake: Carrie comes into the kitchen, visibly hot and sweaty, and says, "Could it be any hotter?" Doug also has a sweat stain on his back and they stick their heads in the freezer. Suddenly Arthur walks in and says, "Do I have the word pushover on my forehead?" Arthur is wearing a thick shirt tucked into long pants and yet is not sweaty. At his age he would be more visibly drained from the heat than both Carrie and Doug. This happens again later in the episode in the garage.

Starring: Kevin James, Jerry Stiller, Leah Remini, Victor Williams
Genres: Comedy
Revealing mistake: When Carrie phones Doug at IPS, Doug goes to press the button on the phone for the correct line, but doesn't press any and continues to talk to Carrie. (00:07:40)
Doug Heffernan: Hey, Deac, let me ask you, do you think Carrie's gained weight?
Deacon Palmer: Say what?
Doug Heffernan: Carrie, my wife, do you think she's gained a little weight, a couple pounds, maybe?
Deacon Palmer: I don't know. Every time I see her she's blocked by you.
Trivia: The house that Doug visits to make a delivery and stays for a while is the same one that is used for the Heffermans' neighbours' house.
Question: Has Carrie's sister, Sara, ever been mentioned again after the first few episodes, and why was she taken off?
Answer: Sara hasn't been mentioned in later episodes, and it suggested in later episodes that she never existed, and that Carrie is an only child. Kevin James stated that the producers couldn't think of an good plots to use with Sara, so they left her out.
