One of my favorites, occurs at their last overnight rest on the approach to Shelob's lair, where Sam says:
'And people will say: "Let's hear about Frodo and the Ring!" And they'll say: "Yes, that's one of my favorite stories. Frodo was very brave, wasn't he dad?" "Yes, my boy, the famousest of the hobbits, and that's saying a lot."'
Followed a short time later by Frodo saying:
'But you have left out one of the chief characters: Samwise the stout-hearted. "I want to hear more about Sam, dad. Why didn't they put in more of his talk, dad? That's what I like, it makess me laugh. And Frodo wouldn't have got far without Sam, would he, dad?"'
Sadly, this part is followed later by Frodo saying:
'...You and I, Sam, are still stuck in the worst places of the story, and it is all too likely that some will say at this point: "Shut the book now, dad; we don't want to read any more." "Maybe." said Sam, "but I wouldn't be one to say that. Things done and over and made into part of the great tales are different."'
Happily, the story was finalized on the Field of Cormallen, in the "Lay of Frodo of the Nine Fingers and the Ring of Doom". *reading
