I urgently needed a few days off work, but I knew the boss would not allow me to take a 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 light bulb 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 Blonde) 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!"
