This is a bit of a strange one…

The picture is of the top of the cubicle divider in one of the Gents toilets in our building. I spotted this a couple of months ago, and noticed that it was still there today, weeks later. So whose it is, and quite how long it’s been there, is a mystery. (And I don’t propose to pick it up to find out!)

Looks to me like a boiled sweet, and it’s only visible from within the cubicle (note the ridge behind the sweet), and only by someone tall. Very strange.
