So, in an attempt to solve that
problem, I came up with an idea.
You know the red human skeleton
picture at the back of the biology
experiment room?

I have decided to use the number
signed on the picture as the pass
number. If you happen to lose the
memo just use the picture.

Well, I don't think you would
ever need to use the emergency
pass number, anyway. But just
in case, now you know. Take it
easy Mr. Careless!
