C:TGGTEWOWB has a sense of humor that is consistently present, but not consistent in tone. It vacillates from the silly to the snarky and back again. I'd say that about half of the item descriptions are or include jokes. Some of them are probably quite bad, by virtue of the shotgunning nature of them, but I'm not worried about that.
The jokes aren't the true purpose of the game, anyhow.
