A few years back
I was having a bit of a clear out of the lab, and at the back of one of the less-used shelves I came across a bottle of liquid. The bottle itself was remarkable, in that it appeared to have been used for whisky in a previous life, and the liquid inside was slightly turbid, and yellow in colour. No label was attached to give a clue as to its nature or composition.

Undaunted, I removed the lid and brought it to my nostrils. A quick whiff and I saturated my olfactory sensors with a characteristic odour, instantly identifying it. I therefore prepared a suitable label and affixed it to the bottle, replacing it on the shelf for the amusement and delectation of future scientists.

And that, dear readers, is how to this day there remains a bottle on a shelf in my lab with the legend "Fusty Pish" on the label.
