It should be noted going into this question- pretty much the entirety of Doctor Who is at the deep end of the weird pool, if you compare it to just about anything else on television. And there's a simple reason for that: That's what it was specifically designed to do. As different as the Verity Lambert era is from the Innes Lloyd, John Nathan Turner, or Russell T. Davies eras, the one thing that they all have in common is that they fundamentally exist to show you unusual places, things, and people (who are also sometimes things.) So you could randomly select 10 30 second clips from any point in Doctor Who's history and have a reasonable assumption that they are going to be fairly bat-s**t crazy compared to, let's say, Hot in Cleveland. (although sometimes Betty White surprises you...) What I'm getting at here is that for a moment to be considered a high water mark of strange in contrast to other Doctor Who... well, we've pretty comprehensively left Kansas by that point. The rules remain the same - We're considering only Nu-Who here (which sadly means we're unable to mention the Zarbi... except that I just did.) And while 'Weird' is less subjective than 'Funny' (and arguably more-so than 'Romantic') these are still my personal choices for most WTF-ness. You may be more well adjusted to these sorts of things than I am. In any case, your choices may vary and please feel free to add them in the comment section. Are you sitting comfortably? Then we'll begin.
10. That's Not Sanitary, Moxx Of Balhoun
Time has dulled the surprise factor of "The End of the World", since we've revisited the time period a few times and become BFFs with The Face of Boe. However, try to think back to 2005 (2007 if you're in America and were strictly ethical about international piracy statutes) and remember what it felt like at the time. This was, if you recall, only the second episode to be made since the TV movie 9 years earlier (which plainly didn't count), so we were in new territory. It's arguably the first proper story of the new series, as "Rose" really exists more as an extended sizzle reel for the new series comfortably masquerading as a remake of "Spearhead from Space" (Look at all the things you'll see this season! Billie Piper! Aliens! Wacky CGI Dustbins!) "Rose" existed to help viewers settle in to the new series, it couldn't risk being too alienating (no pun intended). Which makes Russell T. Davies decision to go for broke with the weird on "The End of the World" curiously brave and commendable. To sum it up - Rose gets taken to the future, told that the Earth is about to explode forever, meets a butt-load of aliens, and watches the Doctor seem to seriously consider having sex with a tree. Then the last human comes in and turns out to be a bitchy trampoline with a catchphrase and some serious self image issues. Then, to cap it off, the formal greetings involve a tiny blue terrier/lawyer on a floating throw pillow who spits in your face by way of saying hello and everyone just sort of rolls with it. Now that's a party.
