Forum:National Television Awards Sketch 2011: Canon?

I've just been looking at the talk page for this sketch and CzechOut expressed a reason why the sketch was deemed as non-canon instantly without discussion. I don't think anything in the sketch contradicts existing continuity apart from, as CzechOut stated on the talk page; Dot Cotton knowing who the Doctor is. Anyway my point is we should discuss whether the story should be accepted as canon or not, opinions? --Revan\Talk 17:43, April 9, 2011 (UTC)
