This is a good advice. I did this a few times(everyone involved understand the situations as jokes and had a good laugh+ it's England,so insta-fired almost doesn't exist), however what's funny for one,is outright scarry to another. I had enough situations where people screw up and think they'll be fired, while nobody is even remotely considering it, so it's better to avoid those kind of jokes altogether. A good rule is that religion, politics, immigration,and the work itself should be left out from any professional setting.
