We found a carton in the recycling once for egg whites, bearing the legend "Ready to Drink!"
In other news, we've just been to my sisters. In preparation for a picnic, she'd bought me a bag of Cadburys Giant Buttons (well, they're bigger than the normal ones, I'd quibble about 'giant'). Anyway, I was restrained on the picnic, and ate a few, and handed a few round and the rest of the bag was resealed and went back in the hamper. Which went back in the car. Which sat in the sun all afternoon.
She put the bag in the fridge, so when I went to it later I found a lump that looked uncannily like one of those clusters of coins retrieved from Pompeii or Hiroshima...
I managed to chop it up and eat it though!
