#8: Instructions
Programmers are so focused on their job; can you blame them for jumping up at every sound? I’m sure this necessary, though somewhat offensive, sign was written after too many interruptions to the holy work of the programmers, but is it necessary to make them out as caged animals in a zoo?

The most curious thing about this curious sign is the incident they mention; what kind of incident? What happened the last time someone knocked loudly on the door? Then again, I’m not sure I want to know the answer. Just like the sign warning against using the microwave at all costs – sometimes it’s better to leave these things unanswered.
