Perhaps they would do well to realize that if someone uses a "joke licence" they are implicitly stating that the code in question, according to their personal standards, probably isn't suitable for production environments. In some offices however, this same code might be viewed as worth trying to build a blockchain currency system with. Coughcough*

Programmers write things all the time that they wouldn't inflict on anyone else. They're written to get a one-time thing done and no more than that, however, they do sometimes realize that someone else might be facing that very same one-time problem, so there's no harm in at least letting other people play with said abomination.
