Character mistake: The woman in the store claims that the umlaut on the shoe size indicates a half size in Europe. This is wrong because the European shoe size system (used in Germany among others) is completely different from the US system. Carrie's 6 1/2 shoes would be a size 39 according to the European system.

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: OK, I read somewhere that penguins are scared of walruses... So get down there and act like a walrus.
Deacon Palmer: OK so the two of us are up for the role of walrus, and I get it?
Trivia: In many episodes when Doug is hurt, startled, angry etc., he will yell "Yuspa." Cathy Yuspa is one of the two writers on the show.
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.
