”It’s snowing still,” said Eeyore gloomily. “So it is.” “And freezing.” “Is it?” “Yes,” said Eeyore. “However,” he said, brightening up a little, “we haven’t had an earthquake lately.” ― A.A. Milne

I didn't realize Eeyore had a sense of humor.

This is from a British standpoint almost a century old. If Eeyore said the exact same thing in California today it just would not seem funny at all.

That's a very good point. Context can make the difference between funny and not funny.

"We haven't had an earthquake lately" does seem like a line from a Quentin Tarantino movie like The Hateful Eight.
