oh.. i was a system administrator once.. but at that time,
thankfully, i was part of the team that designed the system.. we
put so many failsafes and so much redundancies that it could never
fail unless it's the user who was dumb 
the system has been running non-stop, without shutting down since
1998! 
at that time when i was a sys ad, i was paged at around 11:55pm on
a saturday.. and i was in a pub getting blitzed with friends
so i called back, thinking.. *$&^# can't have crashed!!
on the other side, was the team boss of the place, telling me "my
account has been locked because i typed in a wrong password 3
times"
i replied "it's saturday night, it's midnight, i'm at a pub, and
i'm drunk.. i'll fix that when i get back to work on monday.. in
the meantime, get your duty officer to do the work.. he has the
same access"
and i hung up
