Don't lick the shiny salt
Cute tale from one of my new clients, a salt mine in New York. Apparently a miner was sitting on a bench having lunch while a tour of the mine went through a quarter-mile below the surface. A little old lady was enraptured by a shiny hunk of salt emanating from the wall of dirt, so she went over to lick it. She claimed, yup, tastes like salt. Apparently the salt rock was shiny because it had been recently peed on -- the stream must have eroded some of the peripheral dirt....
So we have a new phrase to accompany "don't eat the yellow snow"....
