Rather liked this as a way to start the week (via Only Dead Fish)...
Couple of lessons: 1) give people the chance to do something nice, and most probably will; 2) once people start doing something unexpected, others will join in (obviously it's all in the editing, but that's the impression you get).
PS Have mirrored this over at another of my blogs, which has been mothballed recently, in an attempt to kick start my enthusiasm! So have a look, and we'll see how things go.
