The King of Queens peaked from 2000 - 2003, and the majority of the episodes after that period were really downhill. This is the quintessential example of that. While there were some funny lines the plot and storylines are completely outrageous and are not believable in the least.
King from Seasons 7 to 9 became a very formulaic show that produced generic episode after generic episode. It lost its place a top comedy on TV, and these episodes are not really good to watch in syndication. Nobody can deny The King of Queens' spot in TV history, but this was just an average offering from the program.
