Wouldn't it be great if in every one of those huge open plan offices, each chair had a huge spring under it. And utterly randomly, once or twice a week, it would launch people into the air.
Health and safety nightmare, I know. But when I worked in a big office this was what I spent my days imagining and it brought me great joy, laughter and quite a few strange looks. I thought I'd share.
EDIT: Launchees would yelp. the yelping is what makes it funny.
