Don't use humor in staging either. You might forget to remove it, and suddenly a joke makes it into prod and people are pissed at you. This (possibly) happened

Don't use humor in staging either. You might forget to remove it, and suddenly a joke makes it into prod and people are pissed at you. This (possibly) happened to Riot Games a couple years ago for their yearly predictions for the World Championship; they had some flavor text about the wildcard portion of the tournament being boring or something and people got pissed. They apologized and explained that it had been a joke from dev that made it into prod that shouldn't have ever been published, but...that shouldn't have ever been typed into the computer in the first place.
