Well, I'll always volunteer for the blind stab.

Prunes and prisms:

This phrase says to me people who eat prunes, who are the elderly, but not just the ordinary elderly, but those who live beneath the glow of chandeliers with a wealth of glowing prisms.

Also, prunes makes me think of people with snobbishly pursed mouths--so these old people of chandeliers are definitely snobs with prunishly pursed mouths.

That's Wordwind's take, Bill.
