When I was a young geology student, one of my cousins brought me a bunch of rocks he'd gathered in the tobacco fields to identify.
The group was dominated by quartzite, some white or clear quartz crystals that had been worn round over time, an occasional well weathered bit of mica schist, some limonite (bog iron), and a nice array of rose quartz pebbles. I identified all but the rose quartz pebbles and told him, with complete gravity, that he had a real nice mess of rabbit eggs there.
It was a cute joke, and harmless enough, and I went home.
But about three hours later I got a phone call from my aunt.
My cousin had industriously gone out and gathered every rose quartz pebble he could find and put them in the oven, with it on low, to hatch a bunch of rabbits for himself.
She came home, noticed the oven on, and opened the door to find a pile of rocks inside...
