I brought a similar case up earlier with the pages about Doctor Who spoof The Lollipop Man on Doctors, but there's another number of pages on this wiki that I believe are fundamentally similar in nature, and should probably be deleted, with their basics added to the page Cultural references to the Doctor Who universe.
I think there's a case to be made for keeping BBC-licensed skits involving DW actors playing their DW characters or the TARDIS set. At the very least, Clown Court special (TV story) was included on the DVD for Delta and Bannerman and has just as much a right to be here as any other special feature.
In my opinion, this is a Doctor Who Wiki. Everything Doctor Who, whether valid or invalid, obviously deserves covering to some extent but taking away individual story articles and leaving just a long-winded article is not the answer. It's only a handful of fans like myself who would actually enjoy scrolling through such a long article like that.
This is a Doctor Who wiki, but at some point we have to make decisions about what to cover. It is not necessary to create separate pages for every non-DWU television show/episode that features a mention or even "appearance" by a DWU character. That's what Cultural references to the Doctor Who universe is for.
BBC-licensed skits that are just DW can get a page, but we don't need a page for, say, every Simpsons episode that features a DWU appearance or reference.
