What if SMAUG had gotten The One Ring?

Sauron made the Ring only for himself, never expecting anyone else to wear it. I like CAB's idea connecting the Ring's ability to change size with Sauron's shape-shifting. Great idea, CAB and a quite original one!

Besides, to Sauron, the Ring was not a possible deathly object. As Gandalf says at least two times: Sauron cannot even think of the possibility that someone might want to destroy the Ring rather then using it for himself.

I agree.

Recently on another forum a user has posted this quote, previously unknown to me:

In the passage in NE (p. 118) describing the eyes of Glaurung when Niënor came face to face with him on the hill-top, the words 'they were terrible, being filled with the fell spirit of Morgoth, his master' contain an editorial alteration: the manuscript reads 'the fell spirit of Morgoth, who made him' (cf. IV.128). My father under*lined the last three words in pencil, and faintly and barely legibly at the foot of the page he noted: 'Glaurung must be a demon [??contained in worm form].'

Grey Annals.

So, it seems,unlike Smaug, Glaurung was a wereworm.
