Yes - mine was quite a silly one (although I did not actually press the 
key). A very many years ago I walked into a site that was having some 
problems building their new system. They had it up 2nd level and it was 
running like a dog, so I said to shut it down. They typed SHUTDOWN on the 
2nd level operator console but, because it was running so slow, the 
SHUTDOWN was picked up by the 1st level guest machine and they closed down 
the 1st level system. It took me a while to explain to them that the 
userid they were running in did not need all the privilege classes in 
order to run the commands 2nd level ;-) Once I had succeeded then they 
said 'Oh, we wondered why this kept happening'
