Seriously this is all for a good cause, namely the Royal National Lifeboat Institute (RNLI) which is a must support charity for sailors in the UK. It receives no government funding and is staffed by volunteers who risk their life to save others.
Even here in London - the busiest of all their stations is right here on the Thames. Last year the Tower Bridge site was launched 380 times and rescued 148 people
This Friday they are having a monster fund raiser and they have a widget on their web site that generates three letter acronyms (TLAs), all variations on SOS to be themes for an event. Mostly they make sense, such as Sponsor Our Staff or Sugar Or Spice, but have just spun Shakespeare Over Seconds, which doesn't (to me).
Have fun but give these guys your support.
