So I just read Dick Cavett

on William F. Buckley, Jr. Great blog. If you click on the title of this post it should take you directly to the nytimes.com website.
This was great from the story, a dedication that Buckley once wrote to Cavett in a book:
To Richard, in deepest gratitude for “More in Seurat than in Ingres.” May I use it?
With affection,
Bill

Now, I was really confused as to WTF this means, it's in reference to french painters but what was the play on words on...

somebody posted this in a comment:

It always hurts to have to explain a bon mot, but here goes:

Hamlet: What, look’d he frowningly?
Horatio: A countenance more in sorrow than in anger.

So there you go!
