Years ago, I was at my brother's and we were well oiled - to say the least. He and his wife went to bed but I decided to have another. I fancied a large Bushmills, so found the bottle and luckily found a whiskey tumbler on the worktop. I poured a very large, large one, drank it (tasted a bit funny though) and went to bed.
In the morning my sister-in-law asked where the tumbler containing her contact lenses (in saline) had gone
I offered to let nature takes its course and return them. She declined.
