There are different grades of "fun". You can do silly things at work, name your servers bob and lola, while still serve the functionality and needs of your customers. But hiring an artist to draw the server as ninjas because "they protect our customers"? What kind of value does that bring? And then you write a blog post about it? Seriously?

Knowing when the fun needs to stop is a way to create valuable things in society. I prefer that, compared to living in world where the state of software is so dire because developers are overgrown kids that spend time writing blog posts about how they named their server pikachu because "pikachu is soooooo cute!!!1111"
