Pass Number Memo

The emergency lock system in the biology experiment room can be released with the four digit pass number. I hope you haven't forgotton about it already. I have just received an order from the system administrator requesting us to change the pass number periodically. What bothers me is that you often lose important memos, pass numbers, or even chemicals... 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!
