A couple of years ago I had brought in some eggs for a friend at work. They were brown ones as well as bluegreen ones. A new co-worker saw them and was astounded at the colors. I winked at another co-worker (who also has chickens) and said: "When chickens are sad or depressed they lay blue eggs". She goes: "Really". My other co-worker answered "Yeah, you can tell by the color just how bad they feel". She asks: "Why did they feel so bad? Can you help them feel better?"
Boy it was hard to keep a straight face. We both had to excuse ourselves and take a break, so we could relieve ourselves laughing.
The new worker didn't last at the job long.
