Tolkien's Funny Bone

[Tuor of Gondolin]

What sort of sense of humour did Tolkien have? Why is so little of it displayed in the Legendarium?

Did he leave it out so legions of fanfiction writers in later ages could supply it?

Aren't you forgetting about when Aldarion brought back from
northern Middle-earth a Norwegian Blue Parrot for
Erendis? Sadly, it turned out the parrot was dead, not
resting, and the relationship headed south.
