Getting Crap Past the Radar/Tabletop Games

Tabletop RPGs
"Ha! Did I ever tell you the story of how I stole the giant’s staff and his twin orbs of power?"
 * Dungeons & Dragons:
 * Gary Gygax was putting stuff like this in as early as the First Edition. For example, the Monster Manual 2 write of Glasya gives her 69 hit points. Glasya, to those who don't know, is a Horny Devil known for her diabolical beauty, the accompanying picture showing her using her tail to cover her exposed chest.
 * In the 2nd-edition days of a large number of Forgotten Realms guidebooks (particularly the "Volo's Guides" series of in-universe travelogues) made reference to "festhalls" scattered across the Realms in just about every city and town. And by "festhalls" we mean "brothels".
 * Ed Greenwood himself once actually made a statement to the effect of "TSR won't let us say 'brothel,' so if you see the word 'festhall'..."
 * Made even more blatant by 3rd Edition, when Sharess, goddess of sexual pleasure, also became goddess of festhalls.
 * Races of the Wild mentions that among Raptorans "Age-mates typically marry age-mates of the opposite gender". Since 2 years later WotC went out of their way to veto female players participating in a Reincarnation Romance in Neverwinter Nights 2: Mask of the Betrayer, it's possible this was worded to be about more than ages.
 * In the game Pirates and Plunder, in the rules for port cities, it is explained that when sailors come ashore from the uncultured environment of shipboard, what they most want is to enjoy polite conversation over a cup of tea with a genteel young lady. It then gives a detailed list of the tariffs of the houses providing this service, from your basic cup of tea, up to such pricey luxuries as tea, iced cake, spicy biscuits and extremely refined conversation with two young ladies.
 * The RPG HoL (Human Occupied Landfill) may have been created just to release a supplement titled Buttery WHoLsomeness. Inside contents go straight to Refuge in Vulgarity.
 * The Mutants and Masterminds supplement for comic book fantasy gaming, Warriors and Warlocks, includes a sample character with the following quote.

Wargames

 * In Warhammer there's been a certain iconic image of a Beastman that's appeared in Beastman-related supplements since the Realms of Chaos books...which has a very Refuge in Vulgarity version of "Mary Had A Little Lamb" written on its sword. The pic has lasted through at least seven editions of supplements as the phrase in question is written in the runes of the (in-game Chaos language) Dark Speech, which the editors apparently don't read.
