Not throwing stuff out of windows, but an earlier post reminded me of this rather dull anecdote.
Back when I was a student, I used to earn a bit of cash helping out a mate’s dad who had a coach-works business. Mostly this was either collecting a Transit cab+chassis or delivering said vehicle back with a fresh flatbed / tipper on the back, but we did other odd jobs too.
One day we were tasked with cleaning out the yard, which was a mess of box section offcuts and assorted detritus. I picked up what I thought was a length of PVC piping several feet long and flung it into the Big Pile O’ Crap, only to discover after the effect that it was in fact an incredibly dusty fluorescent tube. There was an astonishingly loud bang like a bloody bomb had gone off, followed by everything going very very quiet indeed. Scared me half to death.
