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: 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.
