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.
The King of Queens (1998)
1 revealing mistake in Art House - chronological order
Starring: Kevin James, Jerry Stiller, Leah Remini, Victor Williams
Genres: Comedy
Two Thirty - S4-E24
Plot hole: In this episode Arthur scams Deacon and several other parents for phony piano lessons because he doesn't actually know how to play the piano. However, earlier in the series (Art House episode, S1 - E24) we learn that Arthur can play the piano when he temporarily moves out and after his house warming party Doug says to Carrie, "Who knew Arthur could play the piano like that?"
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: Were audience members not allowed cameras in the studio? Because there are hardly any pics of the King of Queen's set online. Thanks.
