[pen] Contributuons? Some sort of elementary particle I'm guessing.

Yes.
'Yes' and 'No' are the most basic particles known as contributuons.

Contributuons are not entirely stable. They are sometimes known to decay into mehons, particularly nowadays when enthusiasm is so often considered passé.

We must all don HAZMAT suits immediately, as prolonged exposure to contributuons can cause long term healf effects.

(FGZS) Er, no "h" in healf, BTW. Talking of which, why does anyone working outside seem to have to wear a high-vis jacket? Will it be compulsory for everyone? Should I wear one as a pedestrian? At a recent football match it took six big blokes and a woman, all with this ludicrous garb, to carry an injured footballer off the pitch on a stretcher. You could almost feel the self-importance oozing from the telly screen. After all, this was football, a Very Serious Matter. Come on, you Blues! (whoops).

A high-vis jacket makes a very effective Cloak of Invisibility (I am told) if you want to explore somewhere outside that you're not supposed to be.

(Raak) Mm, I hadn't thought of that. Could be useful for committing gross trespass in railway tunnels. (I have actually done that). It's a bit like donning police uniform without the risk of committing the serious offence of impersonating a police officer. One could get a hard hat as well and be pretty well untouchable. The more I think about it the better it gets. You could give one as a Christmas present to someone with low self-esteem but obviously they would find it difficult to adopt the swagger. Let us raise a glass to The Law of Unintended Consequences.
