[Rumil]

I think there are a few reasons we don't get so much comedy out of the Rohirrim or Gondorians.

First they were in the middle of a war and thus likely less inclined to japes. Also we meet mostly princes, lords and the like, usually in the company of the Great and the Good and in public, where they are trying to be serious and responsible and, as Legate says, using 'higher' or grimmer humour where it occurs.

Beregond, Bergil and Ioreth are the few ordinary folk we meet in Gondor. B&B are naturally a bit subdued with the impending attack and meeting a strange hobbit but Beregond gently ribs Pippin about 'Lesser men do the greater deeds' and Bergil was soon 'laughing and talking gaily' with Pip. I definitely believe Ioreth must have enjoyed a good belly-laugh as much as the next lass!
