Here's a couple of thoughts
-I was seriously impressed and very amused that the Doctor was able to jump start the failed ships engines by putting it into an atmospheric nosedive and (essentially) popping the clutch.
-If your cute and blonde, the Doctor will like you...and most likely something will happen and you'll never see him again. Sucks to be you!
-The Doctor doesn't like people who make fun of fat folks.
-The Doctor is seriously in heat.
The version I watched also added season 4 trailer in the last minute and a half of the clip. I'm looking forward to it. Woo Hoo!
EDIT You can skip youtube and go directly to the official Doctor Who website and watch "Voyage of the Damned" there. Link is in the upper right of screen. Its only good until New Years.
