Armageddon

I keep thinking of a joke from some book I read as a teenager,
or maybe even before that.

There’s a minor crisis, and one character says, “This is
Armageddon,”, and another character replies, “And Armageddon tired
of it.”

I have a vague idea it might have been a Young Adult novel, or
a nursing novel or something, and the second character was the
life-of-the-party type.
