It is a very good advice. The general advice is really to be professional in the workplace. Don't make a joke, unless it is during lunch and you are trying to tell a real joke.
Don't use silly variable names, or add jokes or profanity into your code or documentation.
Sooner or later it will surface and there is NOTHING quite as embarrasing as showing a unknown third party or a manager something on the screen that screams immaturity.
That doesn't mean you shouldn't be able to have fun at the workplace, because you should. Also it makes life at work much easier if everyone has fun- just be professional and respectful.
Also, sometimes you do slip up. Don't be afraid to apologize. It is ok. It is human to make errors, but learn from your mistakes and move on.
