Because it clearly is. If my surname started with an S and I had a kid, I'd totally name them Starfish.

This—the Doctor himself is part of the translation thing, so being near him or the TARDIS works.  I think.

It was a planet, not a sun,so it wasn't really giving anything back to its followers.

The woman at the shop MUST be Sally Sparrow.  Who else works in a shop that might conceivably sell computers and knows the Doctor?  Granted, I have no idea how she'd know the TARDIS phone number or why she'd give it to Oswin, but still.

While I also don't like how this episode sort of awkwardly skips to the end of the Shawn and Juliet plot, I thought that in sheer comedy that this episode was the funniest in a long time. The Geico rhetorical-question-asking-guy was marvelous.
