Sick Leave

I urgently needed a few days off work, but I knew the boss wouldn't allow me to take leave. I thought that maybe if
I acted "CRAZY" then he would tell me to take a few days off.
So I hung upside down on the ceiling and made funny noises.
My co-worker, (who's blonde), asked me what I was doing. I told her that I was pretending to be a lightbulb, so that the boss would think I was "CRAZY",
and give me a few days off.
A few minutes later the boss came into the office and asked
what are you doing? I told him I was a light bulb. He said, you are clearly stressed out. Go home and recuperate for a couple of days. I jumped down and walked out of the office.
When my co-worker(the blond),followed me, the boss asked her and where do you think you're going? She said, I'm going home too, I can't work in the dark!
