I worked at ICL during the 80;s, when the takeover by Fujitsu was announced I wrote a memo from our boss to all the VME support team I worked with informing that 8 am morning exercise sessions would be starting the following month. THe team reaction was hilarious, so much outrage by 10:00. I came clean with my colleagues we all had a good laugh and I thought o more about it.
Two weeks later one of my more notorious colleagues returned from leaver, Mr O'Hooligan started work before me and was literally on the way to berate our manager over 'this latest stupidity' as I walked to my desk. Thankfully I managed to restrain him before he got to our managers office, they had a difficult relationship and the stern telling off about the fictitious exercise sessions would probably lead to Mt O'Hooligan and myself both being fired, him for abusing a senior manager (again) and me for forging company documents (it was a very good spoof).
