The Inklings Laughed

[Galadriel55]

Wow, Bethberry, these books are priceless! (the ones on the website, I mean). No wonder the Inklings laughed over them!

I'm afraid I can't contribute much to answering your question, as I am less than little learned in the historical side of Tolkien, especially in such details as what books made the Inklings laugh. It seems that they enjoyed a dose of self-humour, though, by the words of another Downer:

Alright. While in Oxford, I went there, and heard this story told by the landlord, who heard it from the landlady who owned the Eagle and Child in the days of the Inklings, and who is still alive.
The Story:
C.S. Lewis is sitting down. Tolkien comes in with some papers under his arm. C.S. Lewis looks up innocently and says to him, "Oh no, not another story about elves!"
More of a Lewis story than a Tolkien story, I'll admit, but too good to waste.
