I must agree that it was a rather toughing moment, but I must also agree with
Folwren that in reality, Merry and Pippin should be bowing as well because then it would have shown everyone who really saved Middle-Earth. But I believe,
Folwren, that PJ had all four Hobbits to show that their race isn't as weak as was first thought, and for that matter, a legend. It shows us as the viewers that even the small can be powerful.
