Hell, you can borrow mine. It's the same account I use for movies and shows, to avoid cleaning my place or studying for classes. :P
Anyhow, this show is actually the longest-running and most successful science fiction series of all time, according to the Guinness Book of World Records. It's not surprising to see why, either -- it's really something to behold. The show was really ahead of its time, but now that we are approaching 50 years of the Doctor, capabilities have met up with potential!
If you're new to the show, or a seasoned TARDIS rider, take a look at these excellent, high definition wallpapers with a Doctor Who theme, and maybe you might even find one you like as much as the show itself -- though, I doubt it. ;]
