My department has two emergency numbers, one for office hours (8.45-5.15) and one for the rest of the time. The numbers are 67760 for office hours and 31818 for the rest of the time. In lunch time I’m not sure what we should do.
If we add the number we get 67760 + 31818 = 99578
which is 421 short of 99999. 99999 and 421 are easy to remember. So if you can remember this helpful other numbers and one of the emergency numbers you should easily be able to work out the other one. So now you only have to remember either 31818 or 67760.
