Do you realize that you just said that you said you don't understand humour at all?
All people need to laugh sometimes (except you,maybe) and that's why PJ made Gimli the way he made him.The other characters like that were Merry and Pippin but Gimli with his dwarver accent was (as PJ sees it) a great choice for a funny character.
That's his choice,and you don't need to agree with it,but you can't say that movies don't need humour.Merry and Pippin were same in the books,so Tolkien also knew that the readers need humour.
