Not all Christmas episodes (i.e., episodes that take place around christmas and/or have Christmas as a major theme in the episode) fit the mold of the description. The description says it is supposed to be "divorced from the parent show", a "one-off" and "not part of an ongoing season". This severely limits the trope to the few examples of shows with "special" christmas episodes. Simply having an episode that takes place on christmas is much, much more common and fits the "episodes" index much better. It should be noted that this page has been completely derailed due to this exact idiotic description — many of the examples are simply episodes that take place on Christmas. And splitting the page would be a stupid move, seeing as there are very, very few Christmas episodes that fit the current description. Face it folks — when tropers are so disgusted with a trope's description that they, en masse, decide to ignore it, that means there's something wrong with the trope, not the tropers.
