I have seen the films, just not for a while. I'll have to watch them again! I love the love between Frodo and Sam. (I don't remember if the movies specified the whole "Sam lived out a long and happy life, and then went to be with Frodo forever" thing or not.)

That's slightly more plausible, but without any set-up, not by much. Did he do martial arts as a hobby? Box? Take a self-defense class once? Or does being the hero make you magically good at fighting?
