In the days before refrigerators, dry ice was the lifeblood of the food industry. People would get very emotional when it ran out - often moved to tears - no dry ice to be seen anywhere!

Then there's the story of the guy who after an extremely cold night emerged from under his duvet to find this small block of opaque ice on the floor beside his bed. Wondering were it came from and if it contained anything he turned on the heating and placed it on top of his bedroom radiator to thaw. He then went downstairs to have a hot drink. Ten minutes later he heard this enormously loud fart from behind his bedroom door.

I told you we had a weird sense of humour.
