we wonders, precious, we wonders *gollum*

[Lhunardawen]

This would sound stupid, but i guess the gollum sound came about due to Gollum's excessive fish-eating (or any other meat, for that matter).

IN The Hobbit :

And when he said gollum he made a horrible swallowing noise in his throat. That is how he got his name, though he always called himself "my precious."

So I agree with Imladris that it is not like the sound Gollum made in the movie. And what did he usually swallow? Fish!

Do I make sense?
