This you will find funny........

I worked in a complex that included a Police station, Fire station and court complex. We had  new generators fitted at great expence to run the whole complex. It was down the fire side to test these on a weekly basis....which we did for an hour or so checking output and what have you. they'd trip in fire up first time and run sweetly.  One winter night we had six inches of snow in the city centre ...bringing all the powercables down.  So there we were pop off goes the power, crump rumble the genies trip in running sweetly, there little room lights up like a chrismas tree......but every where else black. The Engineers who fitted them ...never actually hooked them up to the complexes power grid !   we had to use the portable generators form the Fire appliances to provide lighting for the next couple of days ...........along with all the red faces of middle managment who'd been saying the emergency systems were A ok.
