I have about 30 people that report to me and two guys in one area that can't stand each other. It's like dealing with two 9 year old kids every month or two. They are both good machinists although their childish, ongoing crap might get one or both let go someday.
This month's episode has one of them storming in my office accusing the other of going in his toolbox - a big no-no. He said, "As God is my witness, I know Bill took my wrench." After a short pregnant pause I finally said, "Well, I'm going to need more proof than that." He seemed to be taken back by that and then I said, "Why don't you check around your area again and I'll check with Bill."
Bill denied anything and said Mike was delusional. About an hour later Mike walks back in my office and says he found his wrench under his toolbox (which wouldn't surprise me if Bill put it there).
Later on I was thinking about the line "As God is my witness". It's basically saying their invisible friend will magically back them up and because they invoked "God", you're suppose to just respect it as fact.
