I grump to the spouse that my lead on finding the South African chardonnay that we'd tried and liked over the summer had fizzled out.
The spouse: "Hey, NPR announced they're giving away a trip to the Kimberley district, of all places."
Me, grousing through my stuffed nose: "Only if they're throwing in a kimberlite pipe full of gem-quality diamonds."
The spouse stares at me for a moment: "That is serious geologic esoterica."
Me: "And you're surprised I knew it?"
Go listen to some music: "Diamonds Are a Girl's Best Friend" from the album The Magic of Marilyn by Marilyn Monroe.
