Signifying nothing.
The scene is from the TV version. Of course all of the versions are slightly tweaked one from the other.
As a sidestory of this phenomenon, I have to express my regret that one altered line that Douglas Adams approved of never made it to the big screen. In the original Hitchhiker's, way back in the late 70s/early 80s, humans were so amazingly primitive that they still thought digital watches were a pretty neat idea. For the movie he indicated that it should be modernized so we were so amazingly primitive that we still thought cellular telephones were a pretty neat idea. It would've tied in very well with the movie storyline, but too bad, so sad.
So I have a habit of trying to sound clever. How else are you going to know that I am?
