A number of products have been released by White Wolf for April Fools' Day over the years.
These are obviously joke products, although often created in such a way as to actually be useful if people desire to use the information therein.
A special game preview is posted on Justin Achilli's LiveJournal, where health points are called "mortal coil" and the equivalent of Strength is "Nads." Justin claimed it would be a full game at some point. Possibly the first WW April Fools "game."
Developer "Bax Masterson" was also revealed as having been made up by WW staff, after months of mentions in meeting notes and even the occasional product credit.
