"Friend sent me this - he just started as a network engineer. How does this happen?"

Last guy had a system. Now your friend has to break the code. Or break it to the new boss that the last guy is smarter than him/her.

Cat 5 spiders my friend. They catch and devour techs all the time.

He put the wires in his pocket. Then took them out.

But! It's so satisfying when you finally clean it up :D
